Bit Bit Name Initial Value R/W Description
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 12.5, Multi Processor
Communication Function.

Clock Select 0 and 1:
These bits select the clock source for the baud rate
generator.
00: φ clock (n = 0)
01: φ/4 clock (n = 1)
10: φ/16 clock (n = 2)
11: φ/64 clock (n = 3)
For the relationship between the bit rate register setting
and the baud rate, see section 12.3.11, Bit Rate Register
(BRR). n is the decimal representation of the value of n
in BRR (see section 12.3.11, Bit Rate Register (BRR)).
