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.

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.

These bits are a copy of bits B0F10 and B0F11 in FCR1H.
It is possible use these bits as well as the bits B0F10/B1F0 and B0F11/B1F1 in
FCR1H.
To preserve compatibility with the ST10F273E, these bits must be left at their
default value ‘0’ and the FCR1H register must be used.
These bits must be set during a Sector Erase operation to select the sectors to
erase in Bank 0. Besides, during any erase operation, these bits are
automatically set and give the status of the first 10 sectors of Bank 0 (B0F9-
B0F0). The meaning of B0Fy bit for Sector y of Bank 0 is given by
Bank (BxS) and sectors (BxFy) status bits
automatically reset at the end of a Write operation if no errors are detected.
