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.		 fpga_is_funny 5197d 10h /cpu6502_true_cycle/trunk/doc/

18 New directory structure. root 5568d 12h /cpu6502_true_cycle/trunk/doc/
17 CORRECTED "RTI" (wrong: use of stack pointer)
RENAME all states of "FSM Execution Unit" for better reading

13 DELETED directory cpu6502_true_cycle/doc/HTML - use the HTML.RAR file instead fpga_is_funny 5632d 08h /trunk/doc/
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)		 fpga_is_funny 5632d 10h /trunk/doc/

included commits to RCS files with non-trunk default branches.		 fpga_is_funny 5632d 11h /trunk/doc/
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.		 fpga_is_funny 5894d 13h /trunk/doc/
4 Corrected HTML files for documentation (change $log$ to $Log$ in all VHDL files in first release) fpga_is_funny 5903d 11h /trunk/doc/
