Retention of flash data for RA2E1


I am working on RA2E1. When I am storing any data to flash data memory, that data is getting retained but when I apply power cycle at a very fat rate i.e. within 1 second a power cycle is done then it is observed that the data gets erased.

Any suggestions to overcome this issue?

  • After power cycling the RA2E1 device, at which point in the exectuion of the code do you check the data flash? If you look at the data flash content in the debugger before the code has executed to enable the data flash, you will not see the the data you expect.
