9.3.2 I2C Address Selection and Fault Output

ADR/FAULT is an input pin during power up. It can be pulled HIGH or LOW through a resistor as shown in the Typical Applications sections in order to set the I2C address. Pulling this pin HIGH through the resistor results in setting the I2C 7-bit address to 0011011 (0x36), and pulling it LOW through the resistor results in setting the address to 0011010 (0x34).

During power up, the address of the device is latched in, freeing up the ADR/FAULT pin to be used as a fault notification output. When configured as a fault output, the pin will go low when a fault occurs and will return to its default state when register 0x02 is cleared. The behavior of the pin in response to a fault condition is to be pulled low immediately upon an error. The device then waits for a period of time determined by BKND_ERR Register (0x1C) before attempting to resume playback. If the error has been cleared when the device attempts to resume playback, playback will resume, the ADR/FAULT pin will remain high, and normal operation will resume. If the error has not been removed, then the device will immediately re-enter the protected state and wait again for the predetermined period of time to pass. The device will pull the fault pin low for over-current, over-temperature, and under-voltage lock-out.
