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 Bank.
FCR1H (0x08 0006)
Table 11.
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.
Table 12.
Flash data register 0 low
The Flash Address Registers (FARH/L) and the Flash Data Registers (FDR1H/L-FDR0H/L)
are used during the program operations to store Flash Address in which to program and
Data to program.
FDR0L (0x08 0008)

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 a
erase operation if no errors are detected.
Data Input 15:0
These bits must be written with the Data to program the Flash with the following
operations: Word Program (32-bit), Double Word Program (64-bit) and Set
Protection.
