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 1.5 V 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.
