Description
Communication Mode
0: Asynchronous mode
1: Clocked synchronous mode
Character Length (enabled only in asynchronous mode)
0: Selects 8 bits as the data length.
1: Selects 7 bits as the data length.
Parity Enable (enabled only in asynchronous mode)
When this bit is set to 1, the parity bit is added to transmit
data before transmission, and the parity bit is checked in
reception.
Parity Mode (enabled only when the PE bit is 1 in
asynchronous mode)
0: Selects even parity.
1: Selects odd parity.
Stop Bit Length (enabled only in asynchronous mode)
Selects the stop bit length in transmission.
0: 1 stop bit
1: 2 stop bits
For reception, only the first stop bit is checked, regardless
of the value in the bit. If the second stop bit is 0, it is
treated as the start bit of the next transmit character.
Multiprocessor Mode
When this bit is set to 1, the multiprocessor
communication function is enabled. The PE bit and PM
bit settings are invalid in multiprocessor mode. In clocked
synchronous mode, clear this bit to 0.
