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. @ text @ R6502_TC\RegBank_AXY\struct_bd

@First Revision
After the successfully functional test with a SoC of an APPLE][+, I corrected the wrong CVS log entry "$log$" to "$Log$" into all VHDL files. I hope this will not have a bad impact for cpu6502_tc...smile
The CVS history in the VHDL files is fine now.
