) |
Set AES key to dcp_handle_t struct and optionally to DCP.
Sets the AES key for encryption/decryption with the dcp_handle_t structure. The dcp_handle_t input argument specifies keySlot. If the keySlot is kDCP_OtpKey, the function will check the OTP_KEY_READY bit and will return it's ready to use status. For other keySlot selections, the function will copy and hold the key in dcp_handle_t struct. If the keySlot is one of the four DCP SRAM-based keys (one of kDCP_KeySlot0, kDCP_KeySlot1, kDCP_KeySlot2, kDCP_KeySlot3), this function will also load the supplied key to the specified keySlot in DCP.

key | 0-mod-4 aligned pointer to AES key. |
keySize | AES key size in bytes. Shall equal 16. |
