If this bit is set, all flag bits in the STATUS register will be
RW
reset whenever the STATUS register is read over I²C.
RW Reserved. Set to 0.
Sleep After Interrupt. Power down the device at the end
of the ALS cycle if an interrupt has been generated. ⁽¹⁾

(SAI induced sleep)
The way to “wake up” the device from SAI-sleep is by
clearing the interrupt register 0x93.
RW Reserved. Set to 0.
Note(s):
1. SAI does not modify any register bits directly, it rather uses the interrupt signal to turn OFF the oscillator.
