Bit Bit Name
Initial
Value R/W Description
4 O/E 0 R/W Parity Mode (enabled only when the PE bit is 1 in
asynchronous mode)
0: Selects even parity.
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 parity bit is even.
1: Selects odd parity.
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.
3 STOP 0 R/W Stop Bit Length (enabled only in asynchronous
mode)
Selects the stop bit length in transmission.
0: 1 stop bit
1: 2 stop bits
In reception, only the first stop bit is checked. If the
second stop bit is 0, it is treated as the start bit of
the next transmit character.
2 MP 0 R/W Multiprocessor Mode (enabled only in
asynchronous mode)
When this bit is set to 1, the multiprocessor
communication function is enabled. The PE bit and
O/E bit settings are invalid in multiprocessor mode.
For details, see section 15.5, Multiprocessor
Communication Function.
