4.1 PD Controller Application Customization

The PD Controller application binary may be pushed over I2C using the I2Cs port, or the PD controller can read it from an external EEPROM at slave address 0x50 on the I2Cm port. The PD Controller application binary provides a way to customize and initialize the settings of the PD Controller. It allows for any register bit accessible via the Host Interface to be changed before the PD Controller application starts normal operation, to configure system-related settings that must be correct before any application decision is made. TI provides a GUI tool to create the PD Controller application binary.
