Caution When using the LIN function, fix the UAnPS1 and UAnPS0 bits of the UAnCTL0 register to 00.
The parity bit is used to detect bit errors in the communication data. Normally the same parity is used on the
In the case of even parity and odd parity, it is possible to detect odd-count bit errors. In the case of 0 parity and no

(ii) During reception
(i) During transmission
(ii) During reception
During transmission, the parity bit is always made 0, regardless of the transmit data.
During reception, parity bit check is not performed. Therefore, no parity error occurs, regardless of whether the
parity bit is 0 or 1.
No parity bit is added to the transmit data.
Reception is performed assuming that there is no parity bit. No parity error occurs since there is no parity bit.
The number of bits whose value is “1” among the transmit data, including the parity bit, is controlled so as to be
an even number. The parity bit values are as follows.
• Odd number of bits whose value is “1” among transmit data: 1
• Even number of bits whose value is “1” among transmit data: 0
The number of bits whose value is “1” among the reception data, including the parity bit, is counted, and if it is
an odd number, a parity error is output.
Opposite to even parity, the number of bits whose value is “1” among the transmit data, including the parity bit,
is controlled so that it is an odd number. The parity bit values are as follows.
• Odd number of bits whose value is “1” among transmit data: 0
• Even number of bits whose value is “1” among transmit data: 1
The number of bits whose value is “1” among the receive data, including the parity bit, is counted, and if it is an
even number, a parity error is output.
