3.14.2 Operation of Each Circuit

(1) Prescaler
There is a 6-bit prescaler for gen erating a clock to SIO0. The prescaler can be run by
selecting the baud rate generator as the seri al transfer clock.
Table 3.14.1 shows prescaler clock r esolution 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 ou tputs.
