XORsrc LogicalXOR
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 .
StatusFlags: S, Z
Operation: Acc ← Acc XOR src
Encoding: 15 0

Example(s): ; Acc = 2345h
XOR A[2] ; A[2]=0F0Fh; Acc ← 2C4Ah
SpecialNotes: The active accumulator (Acc) is not allowed as the src for this operation .
XORAcc. LogicalXORCarryFlagwithAccumulatorBit
Description: Performs a logical-XOR between the Carry (C) status flag and a specified bit of the active accumu-
lator (Acc .) and returns the result to the Carry .
StatusFlags: C
Operation: C ← C XOR Acc .

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