Turn-on status register (TURN_ON_SR)

Table 33. TURN_ON_SR

FORCED

Reserved

AUTO

VBUS

WKUP

PKEY

•

Address: 0x02

•

Default: 0b1000xxxx where x depends on the turn-on condition

•

Description: Stores last condition, which has turned-on the PMIC.

From the NO_SUPPLY state, if the AUTO_TURN_ON bit is set in the NVM, the TURN_ON_SR [AUTO] is set.

In the OFF state, the TURN_ON_SR is cleared. When a turn-on condition occurs, the related turn-on bit is set in

TURN_ON_SR before leaving the OFF state.

The TURN_ON_SR is cleared in the POWER_DOWN state.

FORCED: The PMIC turn-on condition is triggered by the DFT option

0: False

1: True

VBUS: The PMIC turn-on condition is triggered by the VBUS signal. See Section 5.4.3.1

0: False

1: True

[1]

WKUP: The PMIC turn-on condition is triggered by the WAKEUPn signal. See Section 5.4.3.1

0: False

1: True

[0]

PKEY: The PMIC turn-on condition is triggered by the PONKEYn signal. See Section 5.4.3.1

0: False
