I am developing a routine to write a single word in internal flash.
I've tryed the following code but it doesn't work:
//The sector is already unlocked
pa = (t_WORD *)0xA0000; //High Memory, sector 1
FLASH.MCR.B.PEAS = 0;
FLASH.MCR.B.PGM = 1;
*pa = 0xCAFE; // Data Interlock Write
FLASH.MCR.B.EHV = 1;
FLASH.MCR.B.PEG = 1;
FLASH.MCR.B.EHV = 0;
FLASH.MCR.B.PGM = 0;
The question is that if when the "data interlock" instruction an EXCEPTION IVOR2 arise and the system hang.
What's wrong with the code above?
Thanks to all,
