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.
