80 DGND Ground Ground for DVDD
81 DVDD Power Digital supply voltage (1.8 V)
82 INT1
(AMUTE1)
Digital Output Interrupt pin, can be active low or active
high. When status bits change, this pin is
triggered. The events that trigger an
interrupt are under user control. This pin
can also output an audio mute signal
83 INT2
(AMUTE2)
Digital Output Interrupt pin, can be active low or active
high. When status bits change, this pin is
triggered. The events that trigger an
interrupt are under user control. This pin
can also output an audio mute signal.
I2C LSB selection.
84 INT_TX Digital Output Interrupt. Open drain. A 2 kΩ pull-up
resistor to the microcontroller I/O supply is
recommended.
