Flash control register 1 low (FCR1L)

The Flash control register 1 low (FCR1L) and the Flash control register 1 high (FCR1H) are

used to select the sectors to erase or they are used, during any write operation, to monitor

the status of each sector of the module selected by the SMOD bit of the FCR0H register.

FCR1L is shown below when SMOD = 0 and when SMOD = 1.

B2F[2:0]

Bank 2 XFlash sector 2:0 status

These bits must be set during a sector erase operation to select the

sectors to be erased in Bank 2. During any erase operation, these bits

are automatically set and give the status of the three sectors of Bank 2

(B2F2-B2F0). The meaning of B2Fy bit for sector y of Bank 2 is given in

Table 17. The BTF [2:0] bits are automatically reset at the end of a write

operation if no errors are detected.

B0F[9:0]

Bank 0 IFlash sector 9:0 status

These bits must be set during a sector erase operation to select the

sectors to be erased in Bank 0. During any erase operation, these bits

are automatically set and give the status of the 10 sectors of Bank 0

(B0F9-B0F0). The meaning of B0Fy bit for sector y of Bank 0 is given in

Table 17. The B0F [9:0] bits are automatically reset at the end of a write

operation if no errors are detected.
