FLASH option status register 2
| SRAM1_3_RST | SRAM1 and SRAM3 erase upon system reset Note: SRAM erase is triggered by option byte change operation, when enabling this feature. 0 (B_0x0): SRAM1 and SRAM3 erased when a system reset occurs 1 (B_0x1): SRAM1 and SRAM3 not erased when a system reset occurs |
| SRAM2_RST | SRAM2 erase when system reset Note: SRAM erase is triggered by option byte change operation, when enabling this feature. 0 (B_0x0): SRAM2 erased when a system reset occurs 1 (B_0x1): SRAM2 not erased when a system reset occurs. |
| BKPRAM_ECC | Backup RAM ECC detection and correction disable 0 (B_0x0): BKPRAM ECC check enabled 1 (B_0x1): BKPRAM ECC check disabled |
