The transmission and reception clock pulses used to generate the baud rate are obtained by dividing the
frequency of the main system clock pulse or a signal input to the ASCK pin.
(a)
Generating transmission and reception clock pulses for baud rates based on the main system
clock
The frequency of the main system clock is divided to generate the transmission and reception clock
pulses. The baud rate generated based on the main system clock is determined using the following
expression.
[Baud rate] = f
