Note : Ensure that the power supply rising time is less than the selected oscillation stabilization delay time.
For example, if the main clock frequency F
C
=
10 MHz and 2
14
/F
C
is selected as the oscillation stabilization
delay time, the resulting oscillation stabilization delay time is 1.6 ms. As rapid changes in the power supply
voltage may cause a power-on reset, if you need to change the power supply voltage while the device is
operating, ensure that the power supply voltage changes smoothly.
