Hi,
one example:
//==========================================================================//
// Programs 1 word (16 bits) into the Flash memory //
//==========================================================================//
void
FlashWriteWord (int *Data_ptr, int Word)
{
FCTL3 = 0xa500; // Lock = 0
FCTL1 = 0xa540; // WRT = 1
*Data_ptr = Word; // Program Flash word
FCTL1 = 0xa500; // WRT = 0
FCTL3 = 0xa510; // Lock = 1
return;
}
//==========================================================================//
// Erases 1 Segment of Flash memory //
//==========================================================================//
void
FlashEraseSegment (char *Data_ptr)
{
FCTL3 = 0xa500; // Lock = 0
FCTL1 = 0xa502; // ERASE = 1
*Data_ptr = 0; // Erase Flash segment
FCTL1 = 0xa500; // ERASE = 0
FCTL3 = 0xa510; // Lock = 1
return;
}
