Description

ALS_INT_DIRECT

ALS Interrupt Direct. If asserted, then the INT pin shows the ALS state

directly and it is not necessary to clear the interrupt. If the CLEAR data

exits the threshold range from within, the INT pin is asserted. The

interrupt pin is de-asserted when the CLEAR data re-enters the

threshold range. As long as the CLEAR data is within the thresholds,

the INT pin is not asserted.

ALS_INT_DIRECT_GPIO

ALS Interrupt Direct on GPIO Pin. If asserted, the GPIO pin shows

the ALS interrupt state directly instead of the INT pin. This function

operates in the same manner otherwise as ALS_INT_DIRECT.

PROX_INT_DIRECT

Proximity Interrupt Direct. If asserted, then the INT pin shows the

proximity state directly and it is not necessary to clear the interrupt. If

PDATA crosses the upper threshold from below, the INT pin is

asserted. The interrupt pin is only de-asserted when PDATA crosses

the lower threshold from above. As long as PDATA is below the lower

threshold, the INT pin is not asserted.

PROX_INT_DIRECT_GPIO

Proximity Interrupt Direct on GPIO Pin. If asserted, the GPIO pin

shows the proximity interrupt state directly instead of the INT pin. This

function operates in the same manner otherwise as

PROX_INT_DIRECT.
