Note: Make sure that power supply rises within the selected oscillation stabilization time selected.
For example, when the main clock is operating at F
CH
= 8 MHz and the oscillation stabilization time is 2
12
/F
CH
,
the oscillation stabilization time is 0.5 ms. Therefore, the maximum value of power supply rising time is about
0.5 ms.
When increasing the supply voltage during operation, voltage variation should be within twice the intended
increment so that the voltage rises as smoothly as possible.
