XNOR
Operation
~(RS1 ^ RS2)
~(RD ^ IMM16)
(translates to XNOR RD, #IMM16{15:8]; XNOR RD, #IMM16[7:0])
Performs a bit wise logical exclusive NOR between two 16 bit values and stores the result in the destination
register RD.
Remark: Using R0 as a source registers will calculate the one’s complement of the other source register.
Using R0 as both source operands will fill RD with $FFFF.
