3.5.1MODULATION SCHEMES

Using The FAULT PIN As An Error Indicator:

The A_SEL_FAULTZ pin is the I2C device address select by default. To re-define this pin as an output, write '1'to bit D1 of reg 0X05. Once re-programmed as output, this pin indicates a fault condition. Output will go low for Overcurrent (OC) or undervoltage (UVP) error or overtemperature error (OTE) or overvoltage error
