STATUS (Address 0xfa)

The STATUS register shows the current status of the interface. When released via

IRQ_ENABLE, all the bits can trigger an interrupt.

Reading the STATUS registers only deletes irq_iir_overflow, irq_fifooverflow, and

irq_sequencer.

To delete irq_leadoff, the STATUS_LEADOFF register must be read.

To delete irq_vcsel, the STATUS_VCSEL register must be read.

To delete irq_asat, the STATUS_ASAT register must be read.

To delete irq_lowvds, the STATUS_LED register must be read.

To delete irq_sequencer, the STATUS_SEQ register must be read.

The interrupt for the fill level of the FIFO irq_fifothreshold cannot be deleted directly, but only

by lowering the FIFO level.

Bit description

irq_iir_overflow

Interrupt status bit if the IIR filter block has an overflow

condition.

irq_leadoff

Lead-Off Interrupt.

Check Register STATUS_LEADOFF.

irq_vcsel

VCSEL short to VCSELS/PGND or VCSEL watchdog

detection.

Check Register STATUS_VCSEL,

STATUS_VCSEL_VSS and STATUS_VCSEL_VDD.

irq_asat

Analog Saturation Interrupt.

Check Register STATUS_ASATA and

STATUS_ASATB.

irq_led_lowvds

LED lowvds Interrupt.

Check Register STATUS_LED.

irq_fifooverflow

FIFO overflow occurred. The next sample is lost.

irq_fifothreshold

FIFO is almost full, FIFO_LEVEL >

FIFO_THRESHOLD

irq_sequencer

Sequencer Interrupt.

Check Register STATUS_SEQ.
