MAX5945
when the port is already powered and during shut-
down. PWR_OFF_ is ignored when the port is already
off and during shutdown. After execution, the bits reset
to 0. During detection or classification, if PWR_ON_
goes high, the MAX5945 gracefully terminates the cur-
rent operation and turn-on power to the port. The
MAX5945 ignores the PWR_ON_ in AUTO mode. A
reset sets R19h = 00h.
