Flash control register 1 high
The Flash control register 1 high (FCR1H), together with Flash control register 1 low
(FCR1L), is used to select the sectors to erase, or during any write operation to monitor the
status of each sector and each bank of the module selected by SMOD bit of FCR0H. First
diagram shows FCR1H meaning when SMOD=0; the second one when SMOD=1.

Function
SMOD=0 (XFLASH selected)
B3F(1:0)
B(3:2)S
Bank 3 XFLASH sector 1:0 status
During any erase operation, these bits are automatically set and give the status of the
2 sectors of bank 3 (B3F1-B3F0). The meaning of B3Fy bit for sector y of bank 1 is
given by the next Table 10. These bits are automatically reset at the end of a erase
operation if no errors are detected.
Bank 3-2 status (XFLASH)
During any erase operation, these bits are automatically modified and give the status
of the 2 Banks (B3-B2). The meaning of BxS bit for bank x is given in the next
Table 10. These bits are automatically reset at the end of a erase operation if no errors
are detected.
SMOD=1 (IFLASH selected)
B1F(1:0)
B(1:0)S
Bank 1 IFLASH sector 1:0 status
During any erase operation, these bits are automatically set and give the status of the
2 sectors of bank 1 (B1F1-B1F0). The meaning of B1Fy bit for sector y of bank 1 is
given by the next Table 10. These bits are automatically reset at the end of a erase
operation if no errors are detected.
Bank 1-0 status (IFLASH)
During any erase operation, these bits are automatically modified and give the status
of the 2 banks (B1-B0). The meaning of BxS bit for bank x is given in the next
Table 10. These bits are automatically reset at the end of a erase operation if no errors
are detected.
During any erase operation, these bits are automatically set and give the status of the 2
sectors of Bank 1 (B1F1-B1F0). The meaning of B1Fy bit for sector y of bank 1 is given by
the next Table 10. These bits are automatically reset at the end of a erase operation if no
errors are detected.
