Power Controlling Sequence

The power sequencing of the COMX-P40x0 ENP2 differs between secure boot mode and non-
secure boot mode. For secure boot mode, POVDD should be set to 1.5V DC and is powered at
least 100 system clock cycles after the rising edge of power on reset signal. For non-secure
boot mode, POVDD should be set to GND.
