SET command

Edit online

The SET command transfers the current master-key to the old master-key register, and the new master-key to the current master-key register. It then clears the new master-key register.

The SET command is invoked with Master Key Process (CSNBMKP), and performs these commands:
  1. The master key from the CMK register is copied to the OMK register.
  2. The master key from the FULL NMK register is copied to the CMK register.
  3. The NMK register status is changed to EMPTY.
