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 lim-

ited 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 accumu-

lator (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
