OE = 0: D0–D13 and DOR are high impedance.
OE = 1: All bits are active.
TEST0
Test Pin 0.
Leave unconnected.
CM
Common-Mode Voltage. Analog Input. Drive midway between positive and negative reference
voltages.
RFPF
Positive Reference Voltage. Force Input.
RFPS
Positive Reference Voltage. Sense Input.
RFNF
