Positive power supply input for analog section.
Positive power supply input for speaker amplifiers.

Speaker amplifiers.
Receive data input.
Control clock input. Shifts serially into CI and CO when CS is
low. CCLK is asynchronous with other system clocks.
Chip select input.
Control data input.
Buzzer driver output.
Positive power supply input for the digital section. VCCA,
VCCP AND VCC must be connected together.
Control data output.
Transmit data output. Data is shifted out on this during the
assigned transmit slots. Otherwise, TX is on high impedance
state.
Ground for the digital section.
Frame sync input. This 8kHz signal defines the start of the TX
and RX frames.
