TSL2540 − Register Description

CFG3 Register (Address 0xAB)

Figure 34:

CFG3 Register

The SAI bit sets the device operational mode following the

completion of an ALS cycle. If AINT and AIEN are both set or if

PINT and PIEN are both set, causing an interrupt on the INT pin,

and the SAI bit is set, then the oscillator will deactivate. The

Device will appear as if PON = 0, however, PON will read as 1.

The device can only be reactivated (oscillator enabled) by

clearing the interrupts in the STATUS register.
