NOP
PC ++
No operation and will increase the PC counter by 2
AND Rx,#
Rx <= Rx & Imm
Z
Rx is ANDed with an Immediate 16 or 32 bit value and the result is placed back into Rx.
The Z flag is set if the result is zero.
OR Rx,#
Rx <= Rx | Imm
Rx is ORed with an Immediate 16 or 32 bit value and then result placed back into Rx.
XOR Rx,#
Rx <= Rx ^ Imm
Rx is XORed with an Immediate 16 or 32 bit value and then result placed back into Rx.
BIT Rx,#
Z <= Rx & Imm
Rx is ANDed with an immediate 16 or 32 bit value, but the result is not written back.
This allows testing bits in a register without changing the register's value.
AND Rx,Ry
Rx <= Rx & Ry
Rx is ANDed with Ry and the result placed back into Rx.
The Z flag is set if the result is zero
OR Rx,Ry
Rx <= Rx | Ry
Rx is ORed with Ry and the result is placed back into Rx.
XOR Rx,Ry
Rx <= Rx ^ Ry
Rx is XORed with Ry and the result is placed back into Rx.
BIT Rx,Ry
Rx is ANDed with Ry but the result is not written back.
CRC Rx,Ry,Rz,#n
CRC16's data in RAM at Rx for length Ry using Rz for the CRC accumulator, and polynomial N.
