A dedicated baud rate generator, which consists of a 16-bit programmable counter, generates serial clocks during
Separate 16-bit counters exist for transmission and for reception. The baud rate for transmission/reception is the

Remark
(a) Base clock (Clock)
When UBCTL0.UBPWR bit = 1, the input clock (f
clock is called the base clock. When the UBPWR bit = 0, the clock signal is fixed at low level.
