The baud rate generator selects between 4 clock inputs: φT0, φT2, φT8, and φT32 among
SYSCR<PRCK1:0> is divided by 4 and input to the prescaler as φT0. The prescaler can
be run by selecting the baud rate generator as the serial transfer clock.
There is a 6-bit prescaler for generating a clock to SIO0. The clock selected using
Table 3.9.2 shows prescaler clock resolution into the baud rate generator.
