Access

1: general-purpose output function on GP3 disabled.

GPO2_EN

GP2 GPO Enable Bit. Configures the GP2 pin as a general-purpose output if the higher priority functions are disabled (see

the GPIO section). This bit is only active on the WLCSP option. Setting this bit on the LFCSP option has no effect.

0x0

R/W

0: general-purpose output function on GP2 disabled.

1: general-purpose output function on GP2 enabled.

GPO1_EN

GP1 GPO Enable Bit. Configures the GP1 pin as a general-purpose output if the higher priority functions are disabled (see

the GPIO section). This bit is only active on the WLCSP option. Setting this bit on the LFCSP option has no effect.

0x0

R/W

0: general-purpose output function on GP1 disabled.

1: general-purpose output function on GP1 enabled.

GPO0_EN

BSY_ALT_GP0 GPO Enable Bit. Configures the BSY_ALT_GP0 pin as a general-purpose output if all higher priority

functions are disabled (see the GPIO section).

0x0

R/W

0: general-purpose output function on BSY_ALT_GP0 disabled.

1: general-purpose output function on BSY_ALT_GP0 enabled.

Access

OV_ALT_MODE

OV_ALT Mode Select Bit. This bit configures the OV_ALT bit in the status bits to report the state of the threshold

detection alert indicator (see the Status Bits section).

0x0

R/W

0: does not configure the OV_ALT bit to report the state of the TD_ALERT bit.

1: configures the OV_ALT bit to report the state of the TD_ALERT bit.

RESERVED

Reserved.

0x0

BUSY_GP_SEL

Busy Indicator General-Purpose Pin Select Bit. Selects which general-purpose pin the busy indicator is enabled on

when the BUSY_GP_EN bit is set to 1. This bit is only active on the WLCSP option. Setting this bit on the LFCSP

option has no effect.

0x0

R/W

0: configures BSY_ALT_GP0 as the busy indicator when the BUSY_GP_EN bit is set to 1.

1: configures GP3 as the busy indicator when the BUSY_GP_EN bit is set to 1.

ALERT_GP_SEL

Alert Indicator General-Purpose Pin Select Bit. Selects which general-purpose pin the alert indicator is enabled on

when the ALERT_GP_EN bit is set to 1. This bit is only active on the WLCSP option. Setting this bit on the LFCSP

option has no effect.

0x0

R/W

0: configures BSY_ALT_GP0 as the alert indicator when the ALERT_GP_EN bit is set to 1.

1: configures GP2 as the alert indicator when the ALERT_GP_EN bit is set to 1.
