Function
Analog Output equivalent to the received PCM data for channel 0.
Ground for digital circuit.
Ground for analog circuit.
Negative analog input of the receive OPamp(AMTR0) for channel 0.
Receive gain is defined by the ratio of R4/R3.
R3 is the external input resister connected to this pin.
R4 is the external feedback resister connected between this pin and VR0.
Output of the receive OPamp(AMPR0) for channel 0.
Output of the transmit OPamp(AMPT0) for channel 0.
Positive analog input of the transmit Opamp(AMPT0) for channel 0.
MODE select
0：Register off mode
1：normal mode
Analog ground output.
External capacitance(1.0 uF) should be connected between this pin and AVSS.
