Does the ADuCM322 have a function like programming mode in the mode switching pin setting?

Category: Datasheet/Specs
Product Number: ADuCM322

Hello.

I have a question about ADuCM322.

I have written firmware that performs SystemReset during initialization, and the debugger no longer recognizes the ADuCM322.
As a result, the process to initialize Flash is also not accepted.

We are thinking that if there is a function like Programming mode in the mode switching pin setting of ADuCM332 (e.g., fixing a certain pin to "H"), it would be possible to rewrite the firmware.

Does the ADuCM322 have such a function?

Best regards,
