XOR src
Logical XOR
Description:
Performs a logical-XOR between the active accumulator (Acc or A[AP]) and the specified src data. For the com-
plete list of src specifiers, reference the MOVE instruction. The MAXQ7667 may use the PFX[n] register to supply
the high byte of data for 8-bit sources.
Status Flags:
S, Z
Operation:
Acc
← Acc XOR src
Encoding:
15
0
Example(s):
; Acc = 2345h
XOR A[2]
; A[2]=0F0Fh; Acc
← 2C4Ah
Special Notes:
The active accumulator (Acc) is not allowed as the src for this operation.
XOR Acc.<b>
Logical XOR Carry Flag with Accumulator Bit
Description:
Performs a logical-XOR between the Carry (C) status flag and a specified bit of the active accumulator (Acc.<b>)
and returns the result to the Carry.
Status Flags:
C
Operation:
C
← C XOR Acc.<b>
Encoding:
15
0
Example(s):
; Acc = 2345h, C=1 at start
XOR Acc.1
; Acc.1=0
→ C=1
XOR Acc.2
; Acc.2=1
→ C=0
