TCS3701 − Register O ver view

Status Registers

The primary status register for TCS3701 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 register clears that status bit. In this way, the user

should read the STATUS register, handle all indicated event(s),

then write the register value back to STATUS to clear the

handled events. Writing 0 to these bits 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.

Bit Description

7ASAT

ALS Saturation. If ASIEN is set, indicates ALS

saturation. Check the STATUS2 register to

differentiate between analog or digital saturation.

6PSAT

Proximity Saturation. If PSIEN is set, indicates

analog saturation during a previous proximity cycle.

Check the STATUS3 register to differentiate between

ambient or reflected light saturation.

5PINT1

Proximity Interrupt One. If PIEN1 is set, indicates

that a proximity detect or release event that met the

programmed proximity thresholds (PILT1 or PIHT1)

and persistence (PPERS) occurred.

4PINT0

Proximity Interrupt Zero. If PIEN0 is set, indicates

that a proximity detect or release event that met the

programmed proximity thresholds (PILT0 or PIHT0)

and persistence (PPERS) occurred.

3AINT

ALS Interrupt. If AIEN is set, indicates that an ALS

event that met the programmed ALS thresholds

(AILT or AIHT) and persistence (APERS) occurred.
