You then need to check that the number is between 0 and 127 to ensure it uses only 7 bits. You then need to count the number of 1s in the binary representation of the number. And add 128 to the number to set the parity bit, depending whether you specified odd or even parity.

The 8051 CPU has a hardware parity bit, named 'P', located position b0 of the bit-addressable Special Function Register (SFR) called 'PSW'. The read-only bit 'P' returns a '1' if the number of '1' bits in the accumulator is odd, and returns a '0' if the number of '1' bits in the accumulator is even.

A parity bit, or check bit, is a bit added to a string of binary code. Parity bits are a simple form of error detecting code. Parity bits are generally applied to the smallest units of a communication protocol, typically 8-bit octets (bytes), although they can also be applied separately to an entire message string of bits. The parity bit ensures that the total number of 1-bits in the string is even or odd. Accordingly, ther…
