11.3 Operation of Each Circuit (Channel 0)
11.3.1
Prescaler
The device includes a 7-bit prescaler to generate necessary clocks to drive SIO0. The input
clock φ T0 to the prescaler is selected by SYSCR1 of CG <PRCK2:0> to provide the frequency of
either fperiph/1, fperiph/2, fperiph/4, fperiph/8, fperiph/16 or fperiph/32.
The clock frequency fperiph is either the clock “fgear,” to be selected by SYSCR1<FPSEL> of
CG, or the clock “fc” before it is divided by the clock gear.
The prescaler becomes active only when the baud rate generator is selected for generating the
serial transfer clock. Table 11-2 and Table 11-3 list the prescaler output clock resolution.
