52 / 346 page  Obsolete Product(s) - Obsolete Product(s) Internal Flash memory ST10F296E 52/346 Flash data register 0 low (FDR0L) The Flash address registers (FARH/L) and the Flash data registers (FDR1H/L-FDR0H/L) are used during program operations to store Flash addresses and data to program. FCR1H (0x0E 0006) SMOD = 1 FCR Reset value: 0000h 15 14 13 12 11 10 9 8 76 5432 1 0 Reserved B1S B0S Reserved B1F1 B1F0 - RS RS -RS RS Table 16. FCR1H register description (SMOD = 1, IFlash selected) BIt Bit name Function 15-10 - Reserved 9-8 B[1:0]S Bank 1-0 status (IFlash) During any erase operation, these bits are automatically modified and give the status of the two banks, B1-B0. The meaning of BxS bit for Bank x is given in Table 17. Bits B[1:0]S are automatically reset at the end of a erase operation if no errors are detected. 7-2 - Reserved 1-0 B1F[1:0] Bank 1 IFlash sector 1:0 status 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 1 is given in Table 17. These bits are automatically reset at the end of a erase operation if no errors are detected. Table 17. Banks (BxS) and sectors (BxFy) status bits meaning ERR SUSP BxS = 1 meaning BxFy = 1 meaning 1 - Erase error in Bank x Erase error in sector y of Bank x 0 1 Erase suspended in Bank x Erase suspended in sector y of Bank x 0 0 Don’t care Don’t care FDR0L (0x0E 0008) FCR Reset value: FFFFh 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 DIN 15 DIN 14 DIN 13 DIN 12 DIN 11 DIN 10 DIN 9 DIN 8 DIN 7 DIN 6 DIN 5 DIN 4 DIN 3 DIN 2 DIN 1 DIN 0 RW RW RW RW RW RW RW RW RW RW RW RW RW RW RW RW Table 18.
