; This program is designed to test all additional 65C02 opcodes, addressing
; modes and functionality not available in the NMOS version of the 6502.
; The 6502_functional_test is a prerequisite to this test.
; NMI, IRQ, BRK, STP & WAI are covered in the 6502_interrupt_test.
;
; version 16-aug-2013
; edited to provide a pre-configured bin file loadable at $0000 for full 64k
; contact info at http://2m5.de or email K@2m5.de
;
; assembled with AS65 from http://www.kingswood-consulting.co.uk/assemblers/
; command line switches: -l -m -s2 -w -x -h0
; | | | | | no page headers in listing
; | | | | 65C02 extensions
; | | | wide listing (133 char/col)
; | | write intel hex file instead of binary
; | expand macros in listing
; generate pass2 listing
;
; No IO - should be run from a monitor with access to registers.
; To run load intel hex image with a load command, than alter PC to 400 hex
; (code_segment) and enter a go command.
; Loop on program counter determines error or successful completion of test.
; Check listing for relevant traps (jump/branch *).
; Please note that in early tests some instructions will have to be used before
; they are actually tested!
;
; RESET, NMI or IRQ should not occur and will be trapped if vectors are enabled.
; Tests documented behavior of the original 65C02 only!
; Decimal ops will only be tested with valid BCD operands and the V flag will
; be ignored as it is absolutely useless in decimal mode.
;
; Debugging hints:
; Most of the code is written sequentially. if you hit a trap, check the
; immediately preceeding code for the instruction to be tested. Results are
; tested first, flags are checked second by pushing them onto the stack and
; pulling them to the accumulator after the result was checked. The "real"
; flags are no longer valid for the tested instruction at this time!
; If the tested instruction was indexed, the relevant index (X or Y) must
; also be checked. Opposed to the flags, X and Y registers are still valid.
;
; versions:
; 19-jul-2013 1st version distributed for testing
; 23-jul-2013 fixed BRA out of range due to larger trap macros
