regulator for stabilizing oscillation.
In the S1C63358/63158, it is necessary to switch the V
and operating frequency by controlling the voltage regulator. In the S1C6P366, the V

when using the S1C6P366 as a development tool for the S1C63358/63158, the V
sequence must be implemented according to the model.

2.1.3 Operating mode of power supply circuit
The oscillation system voltage regulator and A/D converter power supply circuit operate in normal

In the S1C63358/63158, a booster mode (V

S1C6P366 is 2.7 V or more, this switching is not necessary and the software control does not affect the
operating mode. However, when using the S1C6P366 as a development tool for the S1C63358/63158, the
operating mode control routine must be implemented according to the model.
