R/W VBAT 2’h1 under voltage occurred.
10: PSON# tri-state 2 sec and then inverted of S3# when over voltage or
under voltage occurred.
11: PSON# tri-state 4 sec and then inverted of S3# when over voltage or
under voltage occurred.
VP_EN_DELAY could set the delay time to start voltage protecting after
VDD power is ok when OVP_MODE is 1. (OVP_MODE is strapped by
RTS1# pin)
