XOR src Logical XOR
Description: Performs a logical-XOR between the active accumulator (Acc or A[AP]) and the specified src
data. For the complete list of src specifiers, reference the MOVE instruction. Because the source
is limited to 8 bits, the PFX[n] register is used to supply the high-byte of data for 16 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>

Example(s): ; Acc = 2345h, C=1 at start
XOR Acc.1 ; Acc.1=0  C=1
XOR Acc.2 ; Acc.2=1  C=0
