16.4 Relationship between main clock and baud rate

The transmit/receive clock that is used to generate the baud
rate is obtained by dividing the main system clock. Trans-
mit/Receive clock generation for baud rate is made by us-

ing main system clock which is divided. The baud rate
generated from the main system clock is determined ac-
cording to the following formula.
