R/W

Sleep After Interrupt. If asserted, the oscillator is turned

off whenever interrupt is active (low). SAI_ ACTIVE is set

in this event. To activate the oscillator again, service and

clear all interrupts plus clear the SAI_ACTIVE bit by

writing “1” to CLEAR_SAI_ACTIVE. Sleep after interrupt

is asserted only in combination with MEASUREMENT_

SEQUENCER_SINT_PER_STEP or SIEN or SIEN_

MEASUREMENT_SEQUENCER
