6 PD
Push-Down Pin. Connect to the external push button. Active high. An internal 100 kΩ pull-down resistor is
connected to GND.
7 PU
Push-Up Pin. Connect to the external push button. Active high. An internal 100 kΩ pull-down resistor is
connected to GND.
8
ASE
Automatic Save Enable. Automatic save enable is configured at power-up. Active low. This pin requires a pull
resistor connected between V
DD
or GND. If ASE is enabled, this pin also indicates when the end scale (maximum
or minimum resistance) has been reached.
EPAD Exposed Pad. The exposed pad is internally floating.
