25 fpga_is_funny 2254d 17h /cpu6502_true_cycle/trunk
24 Bug fix for wrong interrupt sequences in IRQ and NMI. Tested by
simulation with RTI and in a real environment by customer.
Removed directory ./verilog_TRIAL from source.

18 New directory structure. root 5730d 08h /cpu6502_true_cycle/trunk
17 CORRECTED "RTI" (wrong: use of stack pointer)
RENAME all states of "FSM Execution Unit" for better reading
(90%) Finish working for Specification of cpu6502_tc

14 More optimizations...
- Second Phaze of removing unused nets & registers
- Added Verilog source on demand by some customers (for trial use)

11 *** EMERGENCY BUGFIX ***
- Signal rd_o was corrupted in last version. wr_o and wr_n are not effected.
- OP JMP (indirect) produced a 65C02 like jump. On 6502 a special case exist
when the (indirect) address cross the page boundary (e.g. JMP (02FF) reads
from $02FF and $0200, instead of $02FF and $0300)

5 Bugfixes for all relationchips with interrupts BRK, IRQ and NMI.
The control for the stack pointer within fsm*s of BRK, IRQ and NMI was incorrect. The stack was allways growing up instead of growing down.
The "B" status flag was never set within BRK.
The relationchip between addresses and data while writing onto the stack was badly misalligned.
