Chapter 5 XGATE (S12XGATEV2)
XNORH XNORH Logical Exclusive NOR Immediate
8 bit Constant (High Byte)
Operation
~(RD.H ^ IMM8) ⇒ RD.H
Performs a bit wise logical exclusive NOR between the high byte of register RD and an immediate 8 bit
constant and stores the result in the destination register RD.H. The low byte of RD is not affected.
CCR Effects

∆ ∆ 0—
N: Set if bit 15 of the result is set; cleared otherwise.
Z: Set if the 8 bit result is $00; cleared otherwise.
V: 0; cleared.
C: Not affected.
