Flash control register 1 low (FCR1L)
The Flash Control Register 1 Low (FCR1L), together with Flash Control Register 1 High
(FCR1H), is used to select the Sectors to Erase, or during any write operation to monitor the
status of each Sector and Bank.
FCR1L (0x08 0004)
Table 9.
Flash control register 1 high (FCR1H)
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 Bank.
FCR1H (0x08 0006)
Table 10.
During any erase operation, this bit is automatically set and gives the status of the Bank 0.
The meaning of B0Fy bit for Sector y of Bank 0 is given by the next Table 4 Banks (BxS) and
Sectors (BxFy) Status bits meaning. These bits are automatically reset at the end of an
erase operation if no errors are detected.

Bank 0 IFlash Sectors 7-0 Status
These bits must be set during a Sector Erase operation to select the sectors to
erase in Bank 0. Moreover, during any erase operation, these bits are
automatically set and give the status of the eight sectors of Bank 0 (B0F7-B0F0).
The meaning of B0Fy bit for Sector y of Bank 0 is given by the next Table 4 Banks
(BxS) and Sectors (BxFy) Status bits meaning. These bits are automatically reset
at the end of a Write operation if no errors are detected.
Bank 0 Status (IFlash)
During any erase operation, this bit is automatically modified and gives the status
of the Bank 0. The meaning of B0S bit is given in the next Table 4 Banks (BxS)
and Sectors (BxFy) Status bits meaning. This bit is automatically reset at the end
of an erase operation if no errors are detected.
