|
; 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, STP & WAI are covered in the 6502_interrupt_test.

; command line switches: -l -m -s2 -w -x -h0

; | expand macros in 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; flags are no longer valid for the tested instruction at this time!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.

|
|
; added option to skip the remainder of a failing test
|
