(2) Serial clock generation
A serial clock can be generated according to the settings of the UBnCTL2 register.
The 16-bit counter divisor value can be selected according to the UBnCTL2.UBnBRS15 to
UBnCTL2.UBnBRS0 bits.
(a) Baud rate
(b) Baud rate error
Cautions 1. Make sure that the baud rate error during transmission does not exceed the
