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 the SMOD bit). 2. The second step is the definition of the address and data for programming or the sectors or banks to erase. 3. The third instruction is used to start the write operation, by setting the start bit, WMS, in the FCR0 register. 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 Table 34. Table 34.
