IRQ_PRBSI

DAC0 PRBS error. If EN_PRBSI is low, IRQ_

PRBSI shows the current status. If EN_

PRBSI is high, IRQ_PRBSI latches and pulls

the

IRQxE

pin low (x = MUX_PRBSI setting).

Writing a 1 to IRQ_PRBSI when latched

clears the bit.

IRQ_DAC0_CAL_

DONE

DAC0 calibration done. If EN_DAC0_CAL_

DONE is low, IRQ_DAC0_CAL_DONE shows

the current status. If EN_DAC0_CAL_DONE

is high, IRQ_DAC0_CAL_DONE latches and

pulls the

IRQxE

pin low (x = MUX_DAC0_
