Description

CPSAT

Clear Photodiode Saturation. Assertion indicates that the analog sensor

signal reached the upper end of its dynamic range. The bit can be

de-asserted by sending a Clear channel interrupt command (0xE6 CICLEAR)

or by disabling the ADC (AEN=0). This bit triggers an interrupt if CPSIEN is set.

PGSAT

Proximity/Gesture Saturation. Assertion indicates that an analog

saturation event occurred during a previous proximity or gesture cycle. Once

set, this bit remains set until cleared by the clear proximity interrupt

command (0xE5 PICLEAR) or by disabling Proximity (PEN=0). This bit triggers

an interrupt if PSIEN is set.

PINT

Proximity Interrupt. This bit triggers an interrupt if PIEN in ENABLE is set.

AINT

ALS Interrupt. This bit triggers an interrupt if AEN in ENABLE is set.

PBINT

Pattern Burst Interrupt. This bit triggers an interrupt if PBIEN in ICONFIG is

set. (Mirrors PBINT2 bit in CONFIG_A8 register)

GINT

Gesture Interrupt. Assertion indicates that GFVLV has become greater than

GFIFOTH or GVALID has become asserted when GMODE transitioned to zero.

The bit is reset when FIFO is completely emptied (read).

PVALID

Proximity Valid. Indicates that a proximity cycle has completed since PEN

was asserted or since PDATA was last read. A read of PDATA automatically

clears PVALID.

AVALID

ALS Valid. Indicates that an ALS cycle has completed since AEN was asserted

or since a read from any of the ALS/Color data registers.
