Notes: When the smart card interface is used, be sure to make the 1 setting shown for bit 5.
*1 When the PE bit is set to 1, the parity (even or odd) specified by the O/E bit is added to
transmit data before transmission. In reception, the parity bit is checked for the parity
(even or odd) specified by the O/E bit.
*2 When even parity is set, parity bit addition is performed in transmission so that the total
number of 1 bits in the transmit character plus the parity bit is even.
In reception, a check is performed to see if the total number of 1 bits in the receive
character plus the parity bit is even.
*3 When odd parity is set, parity bit addition is performed in transmission so that the total
number of 1 bits in the transmit character plus the parity bit is odd.
In reception, a check is performed to see if the total number of 1 bits in the receive
character plus the parity bit is odd.
