bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit

C = Clear on Read

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

PIN_IGN: Ignores the PWR_EN1 and PWR_EN2 pin states when determining the power state. This bit

is retained in Sleep.

1 = PWR_EN1 and PWR_EN2 pin states are ignored.

0 = Power state is determined by the OR'd combination of the PWR_EN1 and PWR_EN2 pins states

and the corresponding PWR_EN1S and PWR_EN2S bit states.

bit 6

Unimplemented

bit 5

DIS_TO: Disable Time Out - Disables the SMBus time out feature.

1 = Time out disabled

0 = Time out enabled

bit 4-3

Unimplemented

bit 2

BOOST: Indicates that the IBUS current is higher than IBOOST on VBUS1 or VBUS2 (bit is OR’ed).

1 = IBUS has exceeded IBOOST on either or both ports

0 = IBUS is less than IBOOST on either port individually

bit 1-0

Unimplemented: Read as ‘0’
