Command | Arguments | Action | |
---|---|---|---|
B (reak) | <cr> | list break points | |
NNNN | insert break point | ||
-NNNN | delete break point | ||
- | delete all break points | ||
C (all) | <cr> | call routine at PC as subroutine | |
NNNN | call routine at NNNN as subroutine | ||
D (isplay) | NNNN NNNN | display range mod16 | |
NNNN | display 16 bytes [NNNN]mod16 | ||
M | display 16 bytes [M]mod16 | ||
P | display 16 bytes [PC]mod16 | ||
W | display 16 bytes [W]mod16 | ||
@ | following NNNN, M, P, or W displays 16 bytes indirectly | ||
E (ncode) | Encodes a 6809 postbyte based on the addressing mode syntax | ||
G (o) | <cr> | Go to PC | |
NNNN | Go to NNNN | ||
L (oad) | Load a S1-S9 format data | ||
M (emory) | NNNN | Display memory data at address NNNN | |
<cr> | Terminate memory function | ||
/ | Display current byte with address | ||
<lf> | Display next byte with address | ||
Display previous byte with address | |||
, | Skip byte | ||
SPACE | Display next byte | ||
The / may be used as an immediate command. | |||
After any of the display commands the memory contents may be altered by inputting a valid hex number or ascii 'string' enclosed by single quotes ('). | |||
O (ffset) | NNNN NNNN | Calculate the two and/or three byte offset | |
P (unch) | NNNN NNNN | Punch a S1-S9 format data | |
R (egister) | Display 6809 registers and allow changes | ||
<cr> | terminate command | ||
SPACE | terminate value input or skip to next register | ||
, | terminate value input or skip to next register | ||
V (erify) | Verify memory against S1-S9 format data | ||
W (indow) | NNNN | Define a display window for the D and M commands. | |
Ctrl-X will abort any command. |
