work, we offer the next solution:
• The detection of failure will be made with an external LED.
• The output of the flashing code will be via AV1 (pin 10).

Follow the sequence according to the below information, as a guide to fault finding.
1. Unable to read or write into NVM: 66% ON, 33% OFF twice and OFF for a second.
