TPS25751: About register configuration

Part Number: TPS25751

Tool/software:

Hi team,

About this device register configuration, we have two question below.

1. In USBCPD Application Customization Tool, we can export configuration file by full flash binary. Can we use this data as is when MCU boot configuration no EEPROM?
We plan to write this binary data to MCU and boot with MCU.

2. Can we control this Device Functional Modes with GPIO? From TRM p82, there is no GPIO concerned with Device Functional Modes. So, in my understanding it is only method that control device functional mode is using ADCIN1 and ADCIN2. Is this correct?

Please your opinion about above.

    No, when flashing from an MCU you should use the "low region" option. In addition, most use the .C file format to get the image in an array format easily ported to MCU code.

    The dead battery configurations are only configurable through the ADCINx resistors.

    These are specifically for the initial PD behavior when powering up from VBUS, and there is not GPIO associated with these.

    Thanks and Regards,
