PRODUCTION DATA
During the boot procedure, the device will read the ADCINx pins and set the configurations based on the table below. Then it will attempt to load a configuration from an external EEPROM on the I2C3m bus. If no EEPROM is detected, then the device will wait for an EC to load a configuration.
When an external EEPROM is used, each device is connected to a unique EEPROM, it cannot be shared for multiple devices. The external EEPROM shall be at 7-bit slave address 0x50.
| ADCIN1 decoded value (2) | ADCIN2 decoded value (2) | I2C address Index (1) | Dead Battery Configuration |
|---|---|---|---|
| 7 | 5 | #1 | AlwaysEnableSink: 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. |
| 5 | 5 | #2 | |
| 2 | 0 | #3 | |
| 1 | 7 | #4 | |
| 7 | 4 | #1 | SinkRequires_3.0A: The device only enables the sink path if the attached source is offering at least 3.0A. USB PD is disabled until configuration is loaded. |
| 4 | 4 | #2 | |
| 3 | 0 | #3 | |
| 2 | 7 | #4 | |
| 7 | 6 | #1 | SinkRequires_1.5A: The device only enables the sink path if the attached source is offering at least 1.5A. USB PD is disabled until configuration is loaded. |
| 6 | 6 | #2 | |
| 6 | 5 | #3 | |
| 6 | 7 | #4 | |
| 7 | 3 | #1 | NegotiateHighVoltage: The device always enables the sink path during the initial implicit contract regardless of the amount of current the attached source is offering. The PD controller will enter the 'APP ' mode, enable USB PD PHY and negotiate a contract for the highest power contract that is offered up to 20 V. This cannot be used when a patch is loaded from EEPROM. |
| 3 | 3 | #2 | |
| 4 | 0 | #3 | |
| 3 | 7 | #4 | |
| 7 | 0 | #1 | SafeMode: The device does not enable the sink path. USB PD is disabled until configuration is loaded. Note that the configuration could put the device into a source-only mode. This is recommended when the application loads the patch from EEPROM. |
