TDA4VH-Q1: startup issue for TDA4VH

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH

Tool/software:

hello ti expert:

I encountered some issues while debugging TDA4VH, as follows:

1.DEV_REV = 0X82; NVM_CODE_1 = 0x3a; NVM_CODE_2 = 0x3

2. All SOC powers will be pulled up for a few milliseconds and then powered off in sequence, but SOC PORZ has not been pulled up

3. All MCU POWER are powered on normally.

Based on this situation, has TDA4VH entered MCU only mode?

If so, can it be determined that the MCU ONLY was entered due to a malfunction? Or is this NVM set to MCU ONLY by default? Or is it caused by hardware configuration?

Our board is only used for software development and does not test hardware. Is there a simple way to exit MCU ONLY mode and enter normal mode.
