Interrupts

An interrupt output pin INT can be used to interrupt the host. Following interrupt sources are possible:

irq_adc: End of ADC conversion

irq_sequencer: End of sequencer sequence reached.

irq_ltf: A light-to-frequency conversion is finished.

irq_adc_threshold: ADC threshold triggered

– see ADC Threshold.

irq_fifothreshold: FIFO almost full (as defined in bit fifo_threshold)

irq_fifooverflow: FIFO overflow (error condition, data is lost)

irq_clipdetect: TIA output and/or SD output exceeded threshold

– see details in CLIPSTATUS

irq_led_supply_low: led supply low comparator triggered

– see details in LEDSTATUS

Depending on the setting in register INTENAB each of the above interrupt source can assert INT

output pin (active low).

I2C

The AS7038RB includes an I²C slave using an I²C address of 0x30 (7-bit format; R/W bit has to be

added) respectively 60 h (8-bit format for writing) and 61 h (8-bit format for reading). It expects

external pull-up resistors.
