FLASH non-secure OBK configuration register
| LOCK | OBKCFGR lock option configuration bit 0 (B_0x0): FLASH_NSOBKCFGR register unlocked 1 (B_0x1): FLASH_NSOBKCFGR register locked |
| SWAP_SECT_REQ | OBK swap sector request bit 0 (B_0x0): no swap requested 1 (B_0x1): launch the sector swap |
| ALT_SECT | alternate sector bit 0 (B_0x0): current OBK sector is mapped to OBK address range for access 1 (B_0x1): alternate OBK sector is mapped to OBK address range for access |
| ALT_SECT_ERASE | alternate sector erase bit 0 (B_0x0): do not touch OBK sector 1 (B_0x1): erase the alternate OBK sector |
| SWAP_OFFSET | Key index (offset /16 bits) pointing for next swap. 0 (B_0x00): means that no OBK is copied from current to alternate OBK sector during SWAP operation. 511 (B_0x1FF): means that all OBK data (511) are copied |
