SPI memory cryption DPA register
SPI_CRYPT_SECURITY_LEVEL | Set the security level of spi mem cryption. 0: Shut off cryption DPA funtion. 1-7: The bigger the number is, the more secure the cryption is. (Note that the performance of cryption will decrease together with this number increasing) |
SPI_CRYPT_CALC_D_DPA_EN | Only available when SPI_CRYPT_SECURITY_LEVEL is not 0. 1: Enable DPA in the calculation that using key 1 or key 2. 0: Enable DPA only in the calculation that using key 1. |
SPI_CRYPT_DPA_SELECT_REGISTER | 1: MSPI XTS DPA clock gate is controlled by SPI_CRYPT_CALC_D_DPA_EN and SPI_CRYPT_SECURITY_LEVEL. 0: Controlled by efuse bits. |
