Instruction
NOT1 Not Bit
Explanation
Adds the data of general register reg1 to a 16-bit displacement, sign-extended to word length
to generate a 32-bit address. The bit, specified by the 3-bit field “bbb”, is inverted at the byte
data location referenced by the generated address. The bits other than the specified bit are
not affected.
Remark
The Z flag of the PSW indicates whether the specified bit was 0 or 1 before this instruction is
executed, and does not indicate the content of the specified bit after this instruction has been
executed.
