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)
