When active, the serial port is operational.
Interrupt.
Maskable interrupt output. Open drain output for wire-ORed operation.
PCM Bus Clock.
Clock input for PCM bus timing.
Receive PCM Data.
Input data from PCM bus.
Transmit PCM Data.
Output data to PCM bus.
Frame Synch.
8 kHz frame synchronization signal for the PCM bus. May be short or long pulse format.
Reset.
Active low input. Hardware reset used to place all control registers in the default state.
