VSB3V If this bit is set to 1, it mean the chip is in power down mode
VSB3V VID and GPIO function select. This is dedicated pin. if input value is
1(external pull-down 10K), the function is selected to VID. Otherwise, the
input value is 0, the function is selected to GPIO.

I2C_ADDR
RO
VSB3V GPIO serial bus address Select. Internal pull-down 100K ohms are address
0x9C. If external is pull-up 10K ohms, the address is 0x6E. This pin is
trapped during the VSB3VOK.
STS_SLOTOCC
R/W
VBAT
Indicate the SLOTOCC# pin value. This pin will be latched till write this bit
to 1. Writing 0 is invalid.
