CCEN=B_0x0, CCLOCK=B_0x0, KEYLOCK=B_0x0
MCE cipher context 1 configuration register
CCEN | Cipher context enable 0 (B_0x0): If an enabled region selects CTXID=z bypass mode is selected by MCE 1 (B_0x1): If an enabled region selects CTXID=z with ENC=01 MCE selects with the stream cipher the information stored in MCE_CCzCFGR, MCE_CCzNR and MCE_CCzKEYR. If the enabled region selects ENC=10 or 11 instead MCE selects with the block cipher the key information stored in MCE_CCzKEYR. When CCEN is set and MODE[1:0] bits do not allow the configuration written in ENC[1:0] bits (see MODE bitfield) reads return zero and writes are ignored. |
CCLOCK | Cipher context lock 0 (B_0x0): Writes to MCE_CCzCFGR and MCE_CCzNR registers are allowed 1 (B_0x1): Writes to MCE_CCzCFGR and MCE_CCzNR registers are ignored until next MCE reset. |
KEYLOCK | Key lock 0 (B_0x0): Writes to MCE_CCzKEYR registers are allowed 1 (B_0x1): Writes to MCE_CCzKEYR registers are ignored until next MCE reset. KEYCRC bitfield value does not change. |
MODE | Authorized cipher mode 2 (B_0x2): Block cipher is allowed with this cipher context 3 (B_0x3): Fast block cipher is allowed with this cipher context |
