Bank 1 IFlash sector 1:0 status
These bits must be set during a Sector Erase operation to select the sectors to erase in Bank 1.
Besides, during any erase operation, these bits are automatically set and give the status of the two
sectors of Bank 1 (B1F1-B1F0). The meaning of B1Fy bit for Sector y of Bank 0 is given by the
next
reset at the end of a Write operation if no errors are detected.
Bank 0 status
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
meaning. This bit is automatically reset at the end of a erase operation if no errors are detected.
Bank 1 status
During any erase operation, this bit is automatically modified and gives the status of the Bank 1.
The meaning of B1S bit is given in the next
meaning. This bit is automatically reset at the end of a erase operation if no errors are detected.
