6.3.7 Prescaler Clock Control
Each peripheral function has a prescaler for dividing a clock. As the clock φT0 to be input to each prescal-
er, the "fperiph" clock specified in the CGSYSCR<FPSEL[1:0]> can be divided according to the setting in
the
CGSYSCR<PRCK[2:0]>. After the
TMPM3V6/M3V4
is reset, fperiph/1 is selected as φT0.
Note:
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 tim-
er counter or other peripheral function is operating.
6.3.8 System Clock Pin Output Function
This product enables to output the system clock from a pin. The SCOUT pin can output the low speed
clock fs, the system clock fsys and fsys/2, and the prescaler input clock for peripheral functions φT0.
Note 1: The phase difference (AC timing) between the system clock output by the SCOUT and the internal clock
is not guaranteed.
Note 2: When fsys is output from SCOUT pin, SCOUT pin outputs the unexpected waveform just after changing
clock gear. In the case of influencing to system by the unexpected waveform, the output of SCOUT pin
should be disabled when changing the clock gear.
When the port is used as SCOUT pin, refer to "Input/Output port".
Table 6-3 shows the pin status in each mode when the SCOUT pin is set to the SCOUT output.
