Chip Select.
Active low. When inactive, SCLK and SDI are ignored and SDO is high impedance.
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 for-
mat.
Reset.
Active low input. Hardware reset used to place all control registers in the default
state.
DC Monitor.
DC-DC converter monitor input used to detect overcurrent situations in the con-
verter.
