; File created 11-Feb-2012
|
| 49 |
|
|
;
|
| 50 |
|
|
; Modified 09-Dec-2012 mam Changed to a "ROM" type of test program
|
| 51 |
|
|
; where the program is at the top of memory
|
| 52 |
|
|
; and includes the three vectors. Intent is to
|
| 53 |
|
|
; convert core so it indirectly jump through
|
| 54 |
|
|
; the normal processor vectors when an excep-
|
| 55 |
|
|
; is performed: Reset, NMI, or IRQ/BRK.
|
| 56 |
|
|
;
|
| 57 |
|
|
; To make this change need to add code to
|
| 58 |
|
|
; initialize page 0, 1, and 2 RAM locations.
|
| 59 |
|
|
;
|
| 60 |
|
|
; Modified 15-Dec-2012 mam Modified to remove Rockwell instruction op-
|
| 61 |
|
|
; codes from the NOP/Invalid instruction list.
