General-Purpose Logic Input 4. An internal 10μA current source pulls GPI4 to GND.
Configure GPI4 to control watchdog timer functions or the programmable outputs.
General-Purpose Logic Input 3. An internal 10μA current source pulls GPI3 to GND.
Configure GPI3 to control watchdog timer functions or the programmable outputs.
General-Purpose Logic Input 2. An internal 10μA current source pulls GPI2 to GND.
Configure GPI2 to control watchdog timer functions or the programmable outputs.
General-Purpose Logic Input 1. An internal 10μA current source pulls GPI1 to GND.
Configure GPI1 to control watchdog timer functions or the programmable outputs.
Internal Power-Supply Output. Bypass ABP to GND with a 1μF ceramic capacitor. ABP

ABP
powers the internal circuitry of the MAX6872/MAX6873. ABP supplies the input voltage to
the internal charge pumps when the programmable outputs are configured as charge-
pump outputs. Do not use ABP to supply power to external circuitry.
Internal Digital Power-Supply Output. Bypass DBP to GND with a 1μF ceramic capacitor.

DBP
DBP supplies power to the EEPROM memory and the internal logic circuitry. Do not use
DBP to supply power to external circuitry.
