WebJan 1, 2024 · Parity is a control code we can use to prevent errors in data reception or reading on mass memories, adding redundant information. This technique adds to each byte an additional bit , the parity bit. When writing data (bit sequence), we add a control bit set to 0 or 1 after each byte. WebJan 4, 2024 · The start and stop bits are for framing, and not part of the parity calculation. Only the data bits are involved in the parity calculation. The parity bit is an additional bit that is set to a value to make the total count of ones (the parity) to match the parity setting.
