Description
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.
Clock Select 1,0
These bits select the clock source for the on-chip baud
rate generator.
00:
01: /4 clock (n = 1)
10: /16 clock (n = 2)
11: /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.
Description
Transmit Interrupt Enable
When this bit is set to 1, a TXI interrupt request is
enabled.
Receive Interrupt Enable
When this bit is set to 1, RXI and ERI interrupt requests
are enabled.
Transmit Enable
When this bit is set to 1, transmission is enabled.
Receive Enable
When this bit is set to 1, reception is enabled.
