1.6 Power Supply Application/Interruption Procedure
The PFESiP/V850EP1 has two power supply pins: a power supply pin for internal units (IV
pin for external pins (EV
which the operation is guaranteed.
(1) When turning on power
Set to no more than 100 ms the time from when the level of the power supply that starts first becomes 0.1V
until the level of the power supply that starts last becomes 0.9V
