Description
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 frame.
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/( bit settings are invalid in multiprocessor mode.
Clock Select 1,0
These bits select the clock source for the on-chip
baud rate generator.
00: ø clock (n = 0)
01: ø/4 clock (n = 1)
10: ø/16 clock (n = 2)
11: ø/64 clock (n = 3)
For the relation between the bit rate register setting
and the baud rate, see section 15.3.9, Bit Rate
Register (BRR). n is the decimal display of the value
of n in BRR.
