Device Status Registers

The following registers provide status of the device and indicate details about saturation, interrupts,

over temperature, device execution and ambient light flicker detection.

STATUS Register (Address 0x93)

The primary status register for AS7343 indicates if there are saturation or interrupt events that need to

be handled by the user. This register is self-

clearing, meaning that writing a “1” to any bit in the

indicated event(s) and then write the register value back to STATUS to clear the handled events.

Writing “0” will not clear those bits if they have a value of “1”, which means that new events that

occurred since the last read of the STATUS register will not be accidentally cleared. In case channel

saturation has happened (ASAT or FDSAT), it is recommended to discard the measurement results

and re-configure device configuration such as AGAIN and Integration Time to avoid saturation.

Bit Description

ASAT

R, SC

Spectral and Flicker Detect Saturation.

If ASIEN is set, indicates Spectral saturation. Check

STATUS 2 register to distinguish between analog or

digital saturation.

6:4

Reserved

AINT

R, SC

Spectral Channel Interrupt.

If SP_IEN is set, indicates that a spectral event that

met the programmed thresholds and persistence

(APERS) occurred.

FINT

R, SC

FIFO Buffer Interrupt.

If FIEN is set, indicates that the FIFO_LVL fulfills the

threshold condition. If cleared by writing 1, the

interrupt will be asserted again as more data is

collected. To fully clear this interrupt, all data must

be read from the FIFO buffer.

Reserved

SINT

R, SC

System Interrupt.
