Not subjected to production test, verified by design/characterization. However, for applications with strict low
power-down current requirements, it is mandatory that no active voltage source is supplied at any GPIO pin
when VDDP is powered off.
Detection is disabled in power-down mode.
Detection is enabled in both active and power-down mode.
Detection is enabled for external power supply of 5.0V.
The reset of EVR is extended by 300 µs typically after the VDDC reaches the power-on reset voltage.
