Note: Make sure that power supply rises within the oscillation stabilization time selected.
For example, when the main clock is operating at 3 MHz (F
CH
) and the oscillation stabilization time selecting
option has been set to 2
12
/F
CH
, the oscillation stabilization time is 1.4 ms. Therefore, the maximum value of
power supply rising time is about 1.4 ms.
Rapid changes in power supply voltage may cause a power-on reset. If power supply voltage needs to be
varied in the course of operation, a smooth voltage rise is recommended.
