Function
O Analog Output equivalent to the received PCM data for channel 0.
- Ground for digital circuit.
- Ground for analog circuit.
I 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.
O Output of the receive OPamp(AMPR0) for channel 0.
O Output of the transmit OPamp(AMPT0) for channel 0.
I Positive analog input of the transmit Opamp(AMPT0) for channel 0.
I MODE select
0：Register off mode 1：normal mode
O Analog ground output.
External capacitance(1.0 uF) should be connected between this pin and AVSS.
