13.3 Operation of Each Circuit (Channel 0)
13.3.1 Prescaler
The device includes a 7-bit prescaler to generate necessary clocks to drive SIO0. The input clock φT0 to
the prescaler is selected by SYSCR of CG <PRCK1:0> to provide the frequency of either fperiph/2,
fperiph/4, fperiph/8, or fperiph/16.
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 13-1 lists the prescaler output clock resolution.
