______________________________________________________________________________________
Analog Section OK (AOK)
1 = Analog circuitry operating properly.
0 = Analog startup not complete or the MAX9851/
MAX9853 are in shutdown.
AOK reports that the analog section of the MAX9851/
MAX9853 is properly operating. When power is applied
to MAX9851/MAX9853, the AOK bit is set to 0. The
MAX9851/MAX9853 must be taken out of shutdown and
the charge pump must be operating for this bit to be set
to 1. The digital signal processing sections of the
MAX9851/MAX9853 do not operate unless this bit is 1.
Headset Jack Mode Indicator (HSDET)
HSDET reports the load impedance of the four headset
test pins, EXTMICBIASL, EXTMICBIASR, HPL, and
HPR, for use in determining the connected headset
configuration. See Table 3 in the Headset Detect sec-
tion for decoding the value of these bits.

Interrupt Enable Register (0x02)
Clip Detect Interrupt Enable (ICLD)
1 = Detection of clipping triggers a hardware interrupt
and sets CLD (register 0x00, B7).
0 = Clipping not reported.
Slew Detect Interrupt Enable (ISLD)
1 = Completion of a slewed volume change triggers a
hardware interrupt and sets SLD (register 0x00, B6).
0 = Completion of slewing not reported.
Digital PLL Unlock Interrupt Enable (IULK)
1 = An unlock condition in the internal PLLs trigger a
hardware interrupt and sets ULK (register 0x00, B5).
0 = Unlock conditions not reported.
Headset Detect Interrupt Enable (IHSD)
1 = All changes in headset configuration trigger a hard-
ware interrupt and set HSD (register 0x00, B1).
0 = Only jack insertions and removals are reported.
If IHSD = 0 any removal or insertion of a jack (detected
by monitoring EXTMICBIASL) will still trigger an interrupt
on the IRQ line, but other HSDET bit changes will not.
MAX9851: Speaker Fault Interrupt Enable (IFAULT)
1 = Current overload at the Class D speaker amplifier
triggers a hardware interrupt and sets FAULT (register
0x00, B0).
0 = Current overload not reported.
MAX9853: External Fault Interrupt Enable (IFAULT)
1 = Inputs on FAULTIN trigger a hardware interrupt and
set FAULT (register 0x00, B0).
0 = Fault inputs not reported.
