3.14.2 Operation of Each Circuit
(1) Prescaler
There is a 6-bit prescaler for generating a clock to SIO0. The prescaler can be run by
selecting the baud rate generator as the serial transfer clock.
Table 3.14.1 shows prescaler clock resolution into the baud rate generator.

XXX:Don’t care
The baud rate generator selects between 4-clock inputs: φT0, φT2, φT8, and φT32
among the prescaler outputs.
