7.3.10.2.1.4 Pin Strapping to Configure Default Behavior

During the boot procedure, the device reads the ADCINx pins and set the configurations based on the table below. The device then attempts to load a configuration from an external EEPROM on the I2Cc bus. If no EEPROM is detected, then the device waits for an external host to load a configuration.

When an external EEPROM is used, each device is connected to a unique EEPROM, and cannot be shared for multiple devices. The external EEPROM is set at 7-bit target address 0x50.

Table 7-6 Device Configuration using ADCIN1 and ADCIN2
ADCIN1 DECODED VALUE(2)ADCIN2 DECODED VALUE(2)I2C ADDRESS INDEX(1)DEAD BATTERY BOOT CONFIGURATION
75#1AlwaysEnableSink: The device always enables the sink path regardless of the amount of current the attached source is offering. USB PD is disabled until configuration is loaded. This configuration is used with an external embedded controller. The embedded controller manages the battery charger in the system when present.
55#2
20#3
17#4
70#1SafeMode: The device does not enable the sink path. USB PD is disabled until configuration is loaded. Note that the configuration can put the device into a source-only mode. This is recommended when the application loads the patch from EEPROM. SafeMode is recommended when the PD controller manages the battery charger when present.
