*1. Adjustment capacitor for reset output delay time (C_POR) should be connected directly to the CPOR pin and
the VSS pin.
*2. Adjustment capacitor for watchdog output delay time (C_WDT) should be connected directly to the CWDT pin
and the VSS pin.
A capacitor of 100 pF to 1 μF can be used for C_POR and C_WDT.
Caution
The above connection diagram and constant will not guarantee successful operation.
Perform thorough evaluation using the actual application to set the constants.
