Operation of Each Circuit
(1) Prescaler
fc
−
SYSCR1<GEAR2:0> is divided by 8 and input to the prescaler as φT0. The prescaler
can be run only case of selecting the baud rate generator as the serial transfer clock.
φT8, and φT32 among the prescaler outputs.
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.
The serial interface baud rate generator selects between 4 clock inputs: φT0, φT2,
