OPERATION
Configures Behavior of GPIO Pin
Test Mode Halts ADC Operation and Enables Writes to ADC Registers
1 = Enable Test Mode, 0 = Disable Test Mode (Default)
Enables Mass Write Using Address (1011 111)b
1 = Enable Mass Write (Default), 0 = Disable Mass Write
Turns FET On and Off
1 = Turn FET On, 0 = Turn FET Off. Defaults to ON Pin State at End of Debounce Delay
Enables Autoretry After an Overcurrent Fault
1 = Retry Enabled, 0 = Retry Disabled (Default)
Enables Autoretry After an Undervoltage Fault
1 = Retry Enabled (Default), 0 = Retry Disabled
Enables Autoretry After an Overvoltage Fault
1 = Retry Enabled (Default), 0 = Retry Disabled
