1st operand: src8 src16

2nd operand: dst8 dst16

The operand string is interpreted as follows:

a Copy A register in the local 8-bits variable.
|
|
b " B "
|
|
ccr " ccr "
|
|
d " D " " " 16-bits variable.

y " Y "

|
sp " SP "
|
|
pc " PC "
|
|
* 68HC11 page0 memory pointer.
|
|
Get 8-bits page0 offset from program, set up 'addr' local
|
|
variable to refer to the location in page0.
|
|
Copy the 8/16-bits value pointed to by 'addr' in a 8/16-bits variable.
|
|
(x) 68HC11 indirect access with X register.
|
|
Get 8-bits unsigned offset from program, set up 'addr' = X + offset.
|
|
Copy the 8/16-bits value pointed to by 'addr' in a 8/16-bits variable.
|
|
(y) Same as (x) with Y register.
|
|
() 68HC11 extended address mode (global variable).
|
|
Get 16-bits address from program and set 'addr'.
|
|
Copy the 8/16-bits value pointed to by 'addr' in a 8/16-bits variable.
|
|
[] 68HC12 indexed addressing mode
|
|
(sp) Pop
|
|
Pop a 8/16-bits value from stack and set in a 8/16-bits variable.
|
|
r Relative branch
|
|
Get 8-bits relative branch, compute absolute address and set 'addr'
|
|
# 68HC11 immediate value
|
|
Get a 8/16-bits value from program and set a 8/16-bits variable.
|
|
&(x)
|
|
&(y)
|
|
&() Similar to (x), (y) and () except that we don't read the
|
|
value pointed to by 'addr' (ie, only 'addr' is setup). Used by jmp/jsr.
|
|
&[] Similar to [] but don't read the value pointed to by the address.
|
|
, Operand separator.
|
|
- End of input operands.

Example:
|
|
(x),a->a addr = x + (uint16) (fetch8 (proc));
|
|
src8 = a
|
|
*,#,r addr = (uint16) (fetch8 (proc)) <- Temporary 'addr'
|
|
src8 = read_mem8 (proc, addr)
|
|
dst8 = fetch8 (proc)
|
|
addr = fetch_relbranch (proc) <- Final 'addr'
