Write operation summary
In general, each write operation is started through a sequence of three steps:
1.
2.
3.
Once selected, but not yet started, one operation can be canceled by resetting the operation
selection bit.
Available Flash Module Write Operations are summarized in the following

Sector Erase
Set Protection
Program/Erase Suspend
The first instruction is used to select the desired operation by setting its corresponding
selection bit in the Flash Control Register 0.
The second step is the definition of the Address and Data for programming or the
sectors to erase.
The last instruction is used to start the write operation, by setting the start bit WMS in
the FCR0. This last instruction must not be executed from Flash.
