MICBIAS Short Circuit detect IRQ
status
0 = Short Circuit current IRQ not set
1 = Short Circuit current IRQ set
MICBIAS Current detect IRQ status
0 = Current detect IRQ not set
1 = Current detect IRQ set
Write Sequencer Busy IRQ status
0 = WSEQ IRQ not set
1 = WSEQ IRQ set
The Write Sequencer asserts this
flag when it has completed a
programmed sequence - ie it
indicates that the Write Sequencer
is NOT Busy.

0 = GPIO5 IRQ not set
1 = GPIO5 IRQ set
GPIO4 IRQ status
0 = GPIO4 IRQ not set
1 = GPIO4 IRQ set
GPIO3/ADDR IRQ status
0 = GPIO3 IRQ not set
1 = GPIO3 IRQ set
GPIO2/DMIC_DAT IRQ status
0 = GPIO2 IRQ not set
1 = GPIO2 IRQ set
GPIO1/DMIC_LR IRQ status
0 = GPIO1 IRQ not set
