Example 2: Enable Access and Debug Protection.
Example 3: Disable in a permanent way Access and Debug Protection.
Example 4: Enable again in a permanent way Access and Debug Protection, after having
disabled them.
Disable and re-enable of Access and Debug Protection in a permanent way (as shown by
examples 3 and 4) can be done for a maximum of 16 times.
Write operation summary
In general, each write operation is started through a sequence of 3 steps:
1.
2.
3.
Once selected, but not yet started, one operation can be canceled by resetting the operation
selection bit.
A summary of the available Flash Module Write Operations are shown in the following
Table
FCR0H|= 0x0100;/*Set SPR in FCR0H*/
FARL = 0xDFB8;/*Load Add of register FNVAPR0 in FARL*/
FARH = 0x000E;/*Load Add of register FNVAPR0 in FARH*/
FDR0L = 0xFFFC;/*Load Data in FDR0L*/
FCR0H|= 0x8000;/*Operation start*/
FCR0H|= 0x0100;/*Set SPR in FCR0H*/
FARL = 0xDFBC;/*Load Add of register FNVAPR1L in FARL*/
FARH = 0x000E;/*Load Add of register FNVAPR1L in FARH*/
FDR0L = 0xFFFE; /*Load Data in FDR0L for clearing PDS0*/
FCR0H|= 0x8000;/*Operation start*/
FCR0H|= 0x0100;/*Set SPR in FCR0H*/
FARL = 0xDFBC;/*Load Add register FNVAPR1H in FARL*/
FARH
FDR0H = 0xFFFE;/*Load Data in FDR0H for clearing PEN0*/
FCR0H|= 0x8000;/*Operation start*/
The first instruction is used to select the desired operation by setting its corresponding
selection bit in the Flash Control Register 0. This instruction is also used to select in
which Flash Module to apply the Write Operation (by setting/resetting bit SMOD).
The second step is the definition of the Address and Data for programming or the
Sectors or Banks to erase.
The last instruction is used to start the write operation, by setting the start bit WMS in
the FCR0.
