DESCRIPTION
R121 (79h)
Interrupt
Status 1
15
MICSHRT_EINT
0
MICBIAS Short Circuit detect IRQ
status
0 = Short Circuit current IRQ not set
1 = Short Circuit current IRQ set
(Read-Only Register)
14
MICDET_EINT
0
MICBIAS Current detect IRQ status
0 = Current detect IRQ not set
1 = Current detect IRQ set
(Read-Only Register)
13
WSEQ_BUSY_E
INT
0
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.
