; 4.2  C-language Memory model
;====================================================================
 
                                   ;      data      code
#set      SMALL     0              ;     16 Bit    16 Bit
#set      MEDIUM    1              ;     16 Bit    24 Bit
#set      COMPACT   2              ;     24 Bit    16 Bit
#set      LARGE     3              ;     24 Bit    24 Bit
#set      AUTOMODEL 4              ; works always, might occupy two
                                   ; additional bytes
 
 
#set      MEMMODEL  AUTOMODEL      ; <<< C-memory model
 
; The selected memory model should be set in order to fit to the
; model selected for the compiler.
; Note, in this startup version AUTOMODEL will work for all
; C-models. However, if the compiler is configured for SMALL or
; COMPACT, two additional bytes on stack are occupied. If this is not
; acceptable, the above setting should be set to the correct model.
 
;====================================================================
; 4.3  Function-Call Interface
;====================================================================
          #if __REG_PASS__
            .REG_PASS
          #endif
 
; Above statement informs Assembler on compatibility of start-up code
; to  Function Call Interface  as selected for the application. There
; is nothing to configure.
; The Function-Call Interface specifies the method of passing parame-
; ter from function caller to callee.  The standard method of FCC907S
; compiler  uses  "stack argument passing".  Alternatively,  language
; tools can be configured for "register argument passing".
; For details see the compiler manual.
; This start-up file is compatible to both interfaces.
 
;====================================================================
; 4.4  Constant Data Handling
;====================================================================
 
#set      ROMCONST    0            ; works only with compiler ROMCONST
#set      RAMCONST    1            ; works with BOTH compiler settings
#set      AUTOCONST   RAMCONST     ; works with BOTH compiler settings
 
#set      CONSTDATA   AUTOCONST    ; <<< set RAM/ROM/AUTOCONST
 
; - AUTOCONST (default) is the same as RAMCONST
; - RAMCONST/AUTOCONST should always work, even if compiler is set to
;   ROMCONST. If compiler is set to ROMCONST and this startup file is
;   set to RAMCONST or AUTOCONST, this startup file will generate an
;   empty section CINIT in RAM. However, the code, which copies from
;   CONST to CINIT will not have any effect, because size of section is 0.
; - It is highly recommended to set the compiler to ROMCONST for
;   single-chip mode or internal ROM+ext bus. The start-up file
;   should be set to AUTOCONST.
; - ROMCONST setting on systems with full external bus requires exter-
;   nal address mapping.
;   Single-chip can be emulated by the emulator debugger.
;   ROM mirror can also be used with simulator.
;
; see also ROM MIRROR options
 
;====================================================================
; 4.5  Stack Type and Stack Size
;====================================================================
 
#set      USRSTACK      0       ; user stack: for main program
#set      SYSSTACK      1       ; system stack: for main program and interrupts
 
#set      STACKUSE  SYSSTACK    ; <<< set active stack
 
#set      STACK_RESERVE  ON     ; <<< reserve stack area in this module
#set      STACK_SYS_SIZE 1500   ; <<< byte size of System stack
#set      STACK_USR_SIZE 2      ; <<< byte size of User stack
 
#set      STACK_FILL    ON      ; <<< fills the stack area with pattern
#set      STACK_PATTERN 0x55AA  ; <<< the pattern to write to stack
 
; - If the active stack is set to SYSSTACK, it is used for main program
;   and interrupts. In this case, the user stack can be set to a dummy
;   size.
;   If the active stack is set to user stack, it is used for the main
;   program but the system stack is automatically activated, if an inter-
;   rupt is serviced. Both stack areas must have a reasonable size.
; - If STACK_RESERVE is ON, the sections USTACK and SSTACK are reserved
;   in this module. Otherwise, they have to be reserved in other modules.
;   If STACK_RESERVE is OFF, the size definitions STACK_SYS_SIZE and
;   STACK_USR_SIZE have no meaning.
; - Even if they are reserved in other modules, they are still initialised
;   in this start-up file.
; - Filling the stack with a pattern allows to dynamically check the stack
;   area, which had already been used.
;
; - If only system stack is used and SSB is linked to a different bank
;   than USB, make sure that all C-modules (which generate far pointers
;   to stack data) have "#pragma SSB". Applies only to exclusive confi-
;   gurations.
; - Note, several library functions require quite a big stack (due to
;   ANSI). Check the stack information files (*.stk) in the LIB\907
;   directory.
 
;====================================================================
; 4.6  General Register Bank
;====================================================================
 
#set      REGBANK   0           ; <<< set default register bank
 
; set the General Register Bank that is to be used after startup.
; Usually, this is bank 0, which applies to address H'180..H'18F. Set
; in the range from 0 to 31.
; Note: All used register banks have to be reserved (linker options).
 
#if REGBANK > 31 || REGBANK < 0
#  error REGBANK setting out of range
#endif
 
;====================================================================
; 4.7  Low-Level Library Interface
;====================================================================
 
#set      CLIBINIT  OFF         ; <<< select extended library usage
 
; This option has only to be set, if stream-IO/standard-IO function of
; the C-library have to be used (printf(), fopen()...). This also
; requires low-level functions to be defined by the application
; software.
; For other library functions (like e.g. sprintf()) all this is not
; necessary. However, several functions consume a large amount of stack.
 
;====================================================================
; 4.8  Clock Selection
;====================================================================
 
; The clock selection requires that a 4 MHz external clock is provided
; as the Main Clock. If a different frequency is used, the Flash Memory
; Timing settings must be checked!
 
#set      CLOCKWAIT      ON     ; <<< wait for stabilized clock, if
                                ;     Main Clock or PLL is used
 
; The clock is set quite early. However, if CLOCKWAIT is ON, polling
; for machine clock to be switched to Main Clock or PLL is done at
; the end of this file. Therefore, the stabilization time is not
; wasted. Main() will finally start at correct speed. Resources can
; be used immediately.
; Note: Some frequency settings (below) necessarily need a stabilized
; PLL for final settings. In these cases, the CLOCKWAIT setting above
; does not have any effect.
;
; This startup file version does not support subclock.

#set      CLOCK_SPEED     CPU_56MHZ_CLKP2_14MHZ              ; <<< set clock speeds
 
; The peripheral clock CLKP1 is set to the same frequency than the CPU.
; The peripheral clock CLKP2 has its setting. This is because it
; feeds only the CAN controllers and Sound Generators. These do not
; need high frequency clocks.

; One can select which ROM area to mirror into the upper half of bank 00.
; If ROMMIRROR = OFF is selected, the address range 0x008000..0x00FFFF
; shows the contents of the respective area of bank 1: 0x018000..0x01FFFF.
; If ROMMIRROR = ON is selected, the memory bank to mirror can be selected.
; Available banks are 0xF0 to 0xFF. Furthermore, the ROM Mirror area size can
; be selected. 4 sizes are available: 8 kB, 16 kB, 24 kB, or 32 kB. The ROM Mirror
; from the highest address of the selected bank downwards, e.g. if bank 0xFF and
; mirror size 24 kB is selected, the memory range 0xFFA000..0xFFFFFF is mirrored
; to address range 0x00A000..0x00FFFF. The memory area not selected for
; ROM Mirror is still mirrored from bank 0x01.
; This is necessary to get the compiler ROMCONST option working. This is intended
; to increase performance, if a lot of dynamic data have to be accessed.
; In SMALL and MEDIUM model these data can be accessed within bank 0,
; which allows to use near addressing. Please make sure to have the linker
; setting adjusted accordingly!

; However, if no reset vector has been defined on purpose, this start
; address can also be used.
; This mechanism is using the .END instruction at the end of this mo-
; dule. It is not necessary for controller operation but improves
; security during debugging (mainly emulator debugger).
; If the debugger stays here after a single step from label "_start"
; to label "notresetyet", this note can be ignored.
