Serial Channel (SIO)
(1) Input clock
(2) UART mode
14.4.2.2
The baud rate generator uses one of four clocks ( φ T1, φ T4, φ T16 or φ T64) supplied from the prescaler
output clock. This input clock selection is made by setting the baud rate generator control register, BR0CR
<BR0CK1:0>.
Specify the divide ratio of the output clock with the baud rate generator control register
BR0CR<BR0ADDE><BR0S3:0> and the baud rate generator control register 2 BR0ADD<BR0K3:0>.
The baud rate generator divides clocks input from prescaler, and generates transmit and receive clocks.
