Input frequency
to be input to each prescaler, the "fperiph" clock specified in the CGSYSCR<FPSEL> can be divided
according to the setting in the CGSYSCR<PRCK2:0>. After the controller is reset, fperiph is selected as
φT0.
The TMPM370 offers high-speed clock as system clock. The high-speed clock is dividable.
Each peripheral function (TMRB0-7 and SIO0-3) has a prescaler for dividing a clock. As the clock φT0
Note 1 : PLL=ON/OFF setting: available in CGOSCCR<PLLON>
Note 2 : Clock gear setting: available in CGSYSCR<GEAR2:0>

System Clock
Prescaler Clock Control
To use the clock gear, ensure that you make the time setting such that prescaler output
φTn from each peripheral function is slower than fsys (φTn < fsys). Do not switch the
clock gear while the timer counter or other peripheral function is operating.
10MHz
8MHz
Switching of clock gear is executed when a value is written to the CGSYSCR<GEAR2:0>
register. The actual switching takes place after a slight delay.
Input frequency from X1 and X2: 8MHz to 10MHz
