33 / 189 page  ST10F272Z2 Internal Flash memory 33/189 5.4.4 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. 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. 5.4.5 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.
