Bit 5—Parity Enable (PE): In asynchronous mode, selects whether or not parity bit addition is
performed in transmission, and parity bit checking in reception. In clocked synchronous mode,
parity bit addition and checking is not performed, regardless of the PE bit setting.
Note:
Bit 4—Parity Mode (O/E E E E ): Selects either even or odd parity for use in parity addition and
checking.
The O/E bit setting is only valid when the PE bit is set to 1, enabling parity bit addition and
checking, in asynchronous mode. The O/E bit setting is invalid in clocked synchronous mode, and
when parity addition and checking is disabled in asynchronous mode.
Notes: 1. When even parity is set, parity bit addition is performed in transmission so that the total
Bit 3—Stop Bit Length (STOP): Selects 1 or 2 bits as the stop bit length in asynchronous mode.
The STOP bits setting is only valid in asynchronous mode. If clocked synchronous mode is set the
STOP bit setting is invalid since stop bits are not added.

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.
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.
