Posted on September 20, 2007 at 09:17The data sheet of the ST10F271 relating to flash address register low says(page 33):
''Address 15:2
These bits must be written with the Address of the Flash location to program in the following operations: Word Program (32-bit) and Double Word Program (64-bit). In Double Word Program bit ADD2 must be written to ‘0’.''
For
word-programming(32-bit) the address
should be a multiple of
4 (because the two lowest bits of FARL are not writeable they are ignored), for
double word programming (64-bit) the address
must be a multiple of
8.
You can programm 0xAAAABBBB to adress 0x10000 in the following way: first write 0xAAAAFFFF to 0x10000, then write 0xFFFFBBBB to 0x10000. (By the way the way the error flag 10ER in FER will be set at the second write)
I think your approach for programming will also work because the address 0x10002 will be converted into 0x10000.
