; 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 NMOS 6502 only! No unofficial
|
|||
|
; opcodes. Additional opcodes of newer versions of the CPU (65C02, 65816) will
|
|||
|
; not be tested. Decimal ops will only be tested with valid BCD operands and
|
|||
|
; N V Z flags will be ignored.
|
|||
|
;
|
|||
|
; 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; flags are no longer valid for the tested instruction at this time!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.
