Is it possible to update (Self-programming) the firmware that runs on the microcontroller ?For example, I am thinking of receiving data from communication and updating it.
It is possible. The ML62Q1000 series has a self-programming function. For details, refer to "25.3 Self-Programming" in the "ML62Q1000 Series User's Manual". An IAP (In-Application Programming) sample program is provided as a usage example. The IAP sample program is included in the ML62Q1000 series reference software and can be downloaded from the support contents of ML62Q1000 series of our product site.
