Mode input. Used to select between Synchronous Self Clocking (MODE = 1) or Synchronous External Clocking
(MODE = 0) for the Serial Port.
Serial interface clock. Synchronizes serial data transfers. Data is input on the rising edge and output on the falling
edge.
Serial Data Out. Serial data is read from this line when using a 3-wire serial protocol such as the Motorola Serial
Peripheral Interface.
Serial Data IN or OUT. This line is bidirectional programmable and interfaces directly to the Intel Standard Serial
Interface using a 2-wire serial protocol.
Oscillator clock input for the device. A crystal connected between OSC
device, or an external oscillator can drive OSC
Noise Rejection.
Used to connect a crystal source between OSC

Common mode voltage. Must be tied to the mid point of AV
External reference input. Should be negative referenced to V
External reference input. Should be positive referenced to V
Positive analog power supply (+5V).
Active low Reset pin. Used to initialize modulator, filter, RAMs, registers and state machines.
Calibration active output. Indicates that at least one active channel is in a calibration mode.
Multiplexer control output. Indicates that the conversion for the active channel is complete.
Logical channel count output (LSB).
Logical channel count output.
Logical channel count output (MSB).
End of scan output. Signals the end of a channel scan (all active channels have been converted) and data is
available to be read. Remains low until data RAM is read.
I/O reset (active low) input. Resets serial interface state machine only.
Active low chip select pin. Used to select a serial data transfer cycle. When high the SDO and SDIO pins are
three-state.
