EEPROM Ready. Active-Low indicates an ongoing write operation in the EEPROM.

Low Terminal of Resistor B. The voltage at this pin can be greater than or less

than the voltage at pin HIGH. Current can flow into or out of this pin.

Wiper Terminal for Resistor B

High Terminal of Resistor B. The voltage at this pin can be greater than or less

than the voltage at pin LOW. Current can flow into or out of this pin.

Low Terminal of Resistor A. The voltage at this pin can be greater than or less

than the voltage at pin HIGH. Current can flow into or out of this pin.

Wiper Terminal for Resistor A

High Terminal of Resistor A. The voltage at this pin can be greater than or less

than the voltage at pin LOW. Current can flow into or out of this pin.

Mute. Both wiper registers are asynchronously set to zero. Data stored in the

EEPROM is not affected. Active-High signal. Internal pull-down resistor. Can be left

unconnected if not used.

The exposed pad is not internally connected. Connect to GND or leave floating.
