a Copy A register in the local 8-bits variable.

|
|
pc " PC "
|
1257 |
|
|
* 68HC11 page0 memory pointer.
|
1258 |
|
|
Get 8-bits page0 offset from program, set up 'addr' local
|
1259 |
|
|
variable to refer to the location in page0.
|
1260 |
|
|
Copy the 8/16-bits value pointed to by 'addr' in a 8/16-bits variable.
|
1261 |
|
|
(x) 68HC11 indirect access with X register.
|
1262 |
|
|
Get 8-bits unsigned offset from program, set up 'addr' = X + offset.
|
1263 |
|
|
Copy the 8/16-bits value pointed to by 'addr' in a 8/16-bits variable.
|
1264 |
|
|
(y) Same as (x) with Y register.
|
1265 |
|
|
() 68HC11 extended address mode (global variable).
|
1266 |
|
|
Get 16-bits address from program and set 'addr'.
|
1267 |
|
|
Copy the 8/16-bits value pointed to by 'addr' in a 8/16-bits variable.
|
1268 |
|
|
[] 68HC12 indexed addressing mode
|
1269 |
|
|
(sp) Pop
|
1270 |
|
|
Pop a 8/16-bits value from stack and set in a 8/16-bits variable.
|
1271 |
|
|
r Relative branch
|
1272 |
|
|
Get 8-bits relative branch, compute absolute address and set 'addr'
|
1273 |
|
|
# 68HC11 immediate value
|
1274 |
|
|
Get a 8/16-bits value from program and set a 8/16-bits variable.
|
1275 |
|
|
&(x)
|
1276 |
|
|
&(y)
|
1277 |
|
|
&() Similar to (x), (y) and () except that we don't read the
|
1278 |
|
|
value pointed to by 'addr' (ie, only 'addr' is setup). Used by jmp/jsr.
|
1279 |
|
|
&[] Similar to [] but don't read the value pointed to by the address.
|
1280 |
|
|
, Operand separator.
|
1281 |
|
|
- End of input operands.
|
1282 |
|
|
|
1283 |
|
|
Example:
|
1284 |
|
|
(x),a->a addr = x + (uint16) (fetch8 (proc));
|
1285 |
|
|
src8 = a
|
1286 |
|
|
*,#,r addr = (uint16) (fetch8 (proc)) <- Temporary 'addr'
|
1287 |
|
|
src8 = read_mem8 (proc, addr)
|
1288 |
|
|
dst8 = fetch8 (proc)
|
1289 |
|
|
addr = fetch_relbranch (proc) <- Final 'addr'
|
1290 |
|
|
|
1291 |
|
|
Returns 1 if the 'addr' operand is set, 0 otherwise. */
