MAXQ7665/MAXQ7666 User’s Guide
14-32
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 MAXQ7665/MAXQ7666 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
