Section 10 Serial Communication Interface
Bit 5: Parity enable (PE)
Bit 5 selects whether a parity bit is to be added during transmission and checked during reception
in asynchronous mode. In synchronous mode parity bit addition and checking is not performed,
irrespective of the bit 5 setting.

Bit 4: Parity mode (PM)
Bit 4 selects whether even or odd parity is to be used for parity addition and checking. The PM bit
setting is only valid in asynchronous mode when bit PE is set to 1, enabling parity bit addition and
checking. The PM bit setting is invalid in synchronous mode, and in asynchronous mode if parity
bit addition and checking is disabled.

2. For the case where 5-bit data is selected, see table 10.11.
2. When odd parity is selected, a parity bit is added in transmission so that the total
data before it is sent, and the received parity bit is checked against the parity
designated by bit PM.
number of 1 bits in the transmit data plus the parity bit is an even number; in reception,
a check is carried out to confirm that the number of 1 bits in the receive data plus the
parity bit is an even number.
number of 1 bits in the transmit data plus the parity bit is an odd number; in reception, a
check is carried out to confirm that the number of 1 bits in the receive data plus the
parity bit is an odd number.
