(6) Parity types and corresponding operation
A parity bit is used to detect a bit error in communication data. Normally, the same type of parity bit is used on
the transmission and reception sides.
(a) Even parity
(b) Odd parity
(c) 0 parity
(d) No parity
(i) During transmission
(ii) During reception
(i) During transmission
(ii) During reception
During transmission the parity bit is set to “0” regardless of the transmit data.
During reception, no parity bit check is performed. Therefore, no parity error is generated regardless of
whether the parity bit is “0” or “1”.
No parity bit is added to the transmit data.
During reception, the receive operation is performed as if there were no parity bit. Since there is no parity
bit, no parity error is generated.
The parity bit is controlled so that the number of bits with the value “1” within the transmit data
including the parity bit is even. The parity bit value is as follows.
• If the number of bits with the value “1” within the transmit data is odd: 1
• If the number of bits with the value “1” within the transmit data is even: 0
The number of bits with the value “1” within the receive data including the parity bit is counted, and a
parity error is generated if this number is odd.
In contrast to even parity, the parity bit is controlled so that the number of bits with the value “1” within
the transmit data including the parity bit is odd. The parity bit value is as follows.
• If the number of bits with the value “1” within the transmit data is odd: 0
• If the number of bits with the value “1” within the transmit data is even: 1
The number of bits with the value “1” within the receive data including the parity bit is counted, and a
parity error is generated if this number is even.
