4 PTCH Mode to APP Mode

The patch bundle is a binary image which includes (bundles) both the device configuration and the firmware updates (patch). Section 4.2 shows how to generate the patch bundle, also referred to as the low region binary. Section 4.1 steps through the Patch Burst Mode (PBM) process and the resulting transition from PTCH to APP mode. A general description of the PBM can be found in the TRMs of the PD controllers and this example follows the same description with the exception of using interrupts. The steps include how to set up and maintain interrupts during the PBM process.

The flow chart in Pushing a Patch Bundle Over the I2Ct Bus assumes that there is no EEPROM present and the START is a cold boot or hard reset of the PD controller.
