Reserved. Must be set to default value.

HOLD_ONLY_IN_

PULSE_ST

0RW

It is recommended to set the bit to “1” during device

initialization. In concurrent mode, ALS integration is

only on hold during Proximity pulsing period.

If the bit is “0”, in concurrent mode, ALS integration is

on hold until Proximity completes the entire

measurement which includes the initialization time,

integration time or PTIME whichever is longer,

hardware averaging loops if enabled and ADC

conversion time. Also ALS is kept on hold during

proximity is waiting for VSYNC signal detection and

PSD time when PVSYNC is enabled.

Reserved

Reserved. Must be set to default value.

SKIP_IDAC_SAR

If set, the IDAC_SAR is skipped.

0DISABLE_IDAC

If set, the IDAC is disabled.

If SKIP_IDAC_SAR =DISABLE_IDAC =0, it enables the

IDAC to automatically remove most of the ambient IR

light to avoid a saturation caused by high ambient IR

components. The function runs before every PTIME,

and the time required is given by the formula: prox_

init_time =7 x(PPULSE_LEN +42.15μs). It may increase

PDATA noise.
