ENC=B_0x0
OTFDEC control register
| ENC | Encryption mode bit When this bit is set, OTFDEC is used in encryption mode, during which application can write clear text data then read back encrypted data. When this bit is cleared (default), OTFDEC is used in decryption mode, during which application only read back decrypted data. For both modes, cryptographic context (keys, nonces, firmware versions) must be properly initialized. When this bit is set, only data accesses are allowed (zeros are returned otherwise, and XONEIF is set). When MODE = 11, enhanced encryption mode is automatically selected. Note: When ENC bit is set, no access to OCTOSPI must be done (registers and Memory mapped region). 0 (B_0x0): OTFDEC working in decryption mode 1 (B_0x1): OTFDEC working in encryption mode |
