Description
Stop Bit Length
Selects one or two bits as the stop bit length.
In receiving, only the first stop bit is checked,
regardless of the STOP bit setting. If the second stop
bit is 1, it is treated as a stop bit, but if the second stop
bit is 0, it is treated as the start bit of the next incoming
character.
This setting is only valid in asynchronous mode. In
synchronous mode, this setting is invalid since stop
bits are not added.
0: One stop bit*
1: Two stop bits*
Notes: 1. In transmitting, a single bit of 1 is added at
Reserved
This bit is always read as 0. The write value should
always be 0.
Clock Select 1 and 0
These bits select the internal clock source of the on-
chip baud rate generator.
00: Pφ
01: Pφ/4
10: Pφ/16
11: Pφ/64
2. In transmitting, two bits of 1 are added at
the end of each transmitted character.
the end of each transmitted character.
