; Modified and adapted from http://www.6502.org/tutorials/decimal_mode.html#B
;
; Verify decimal mode behavior
; Written by Bruce Clark. This code is public domain.
;
; Returns:
; ERROR = 0 if the test passed
; ERROR = 1 if the test failed
;
; This routine requires 17 bytes of RAM -- 1 byte each for:
; AR, CF, DA, DNVZC, ERROR, HA, HNVZC, N1, N1H, N1L, N2, N2L, NF, VF, and ZF
; and 2 bytes for N2H
;
; Variables:
; N1 and N2 are the two numbers to be added or subtracted
; N1H, N1L, N2H, and N2L are the upper 4 bits and lower 4 bits of N1 and N2
; DA and DNVZC are the actual accumulator and flag results in decimal mode
; HA and HNVZC are the accumulator and flag results when N1 and N2 are
; added or subtracted using binary arithmetic
; AR, NF, VF, ZF, and CF are the predicted decimal mode accumulator and
; flag results, calculated using binary arithmetic
;
; This program takes approximately 1 minute at 1 MHz (a few seconds more on
; a 65C02 than a 6502 or 65816)
;
