Bit Description

irq_fifothreshold

R_PUSH1

FIFO is almost full (as defined in

fifo_threshold, usually 3/4)

irq_adc_threshold

R_PUSH1

The ADC value was above the

programmed adc_threshold register

setting

irq_ltf

R_PUSH1

LTF measurement is done. check

LTFSTATUS (or ignore it)

irq_sequencer

R_PUSH1

All configured sequencer iterations

have finished

irq_adc

R_PUSH1

ADC has finished

The STATUS register shows the current state of the interface. Some bits in here can trigger an

interrupt.

An asserted bit can be cleared by writing a '1' to it - in case of irq_led_supply_low and irq_clipdetect,

this also clears the underlying condition in the CLIPSTATUS and LEDSTATUS registers.

The FIFO threshold interrupt cannot be cleared directly, but only by lowering the FIFO level. The FIFO

overflow interrupt is sticky and must be cleared explicitly.
