Bit 2—Multiprocessor Mode (MP): Selects a multiprocessor format. When a multiprocessor
format is selected, parity settings made by the PE and O/E bits are ignored. The MP bit setting is
valid only in asynchronous mode. It is ignored in synchronous mode.
For further information on the multiprocessor communication function, see section 11.3.3,
Multiprocessor Communication Function.

Bits 1 and 0—Clock Select 1 and 0 (CKS1/0): These bits select the clock source of the on-chip
baud rate generator. Four clock sources are available: ø, ø/4, ø/16, and ø/64.
For the relationship between the clock source, bit rate register setting, and baud rate, see section
11.2.8, Bit Rate Register.
