Interrupt mask register bits serve as a mask for the interrupt sources in the interrupt status registers. Interrupts are described in Section 4.3.
Registers at addresses 0x35 and 0x36 must not be part of a control-port autoincremented read and must be read individually. See Section 4.14.

Interrupt status bits are read only and sticky. Interrupts are described in Section 4.3. Registers at addresses 0x35 and 0x36 must not be part
of a control-port autoincremented read and must be read only individually. See Section 4.14.
Bits Name Description
7 PDN_
DONE
Power down done. Indicates when the device
has powered down and MCLK can be stopped.
0 Not completely powered down
1 Powered down as a result of PDN_ULP having been set
6THMS_
TRIP
Thermal sensor trip. If thermal sensing is enabled, this bit indicates whether the current junction temperature has exceeded
the safe operating limits. See Section 4.11.
0 Junction temperature is within safe operating limits.
1 Junction temperature has exceeded safe operating limits.
5SYNC_
DONE
Multichip synchronization sequence done. Indicates that the device has received and confirmed the synchronization protocol.
0 SYNC protocol has not been received.
1 SYNC protocol has been received and confirmed.
4:1 ADCxy_
OVFL
Indicates the overrange status in the corresponding signal path. Rising-edge state transitions may cause an interrupt,
depending on the programming of the associated interrupt mask bit.
0 No digital clipping has occurred in the data path of the indicated digital ADC
1 Digital clipping has occurred in the data path of the indicated digital ADC
0MUTE_
PIN
MUTE pin asserted. Indicates that the MUTE pin has been asserted.
0 MUTE pin not asserted
1 MUTE pin asserted
