SDAis the data line for the control port.79 SCL Digital Input I2C port serial clock input. SCL is the clockline for the control port.80 DGND Ground Ground for DVDD81 DVDD Power Digital supply voltage (1.8 V)82 INT1(AMUTE1)Digital Output Interrupt pin, can be active low or activehigh. When status bits change, this pin istriggered. The events that trigger aninterrupt are under user control. This pincan also output an audio mute signal83 INT2(AMUTE2)Digital Output Interrupt pin, can be active low or activehigh. When status bits change, this pin istriggered. The events that trigger aninterrupt are under user control. This pincan also output an audio mute signal.I2C LSB selection.84 INT_TX Digital Output Interrupt. Open drain. A 2 kΩ pull-upresistor to the microcontroller I/O supply isrecommended.85 DGNDIO Ground Ground for DVDDIO86 DVDDIO Power Digital I/O supply voltage (3.3 V)
