Write operation summary
In general, each write operation is started through a sequence of 3 steps:
1.
The first instruction is used to select the desired operation by setting its corresponding
selection bit in the Flash Control Register 0.
2.
The second step is the definition of the Address and Data for programming or the
Sectors or Banks to erase.
3.
The last instruction is used to start the write operation, by setting the start bit WMS in
the FCR0.
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
