Re bit 02:
If it has already been activated, know-how protection can be temporarily deactivated by entering the valid password
in p7766. In this case, bit 1 = 0 and bit 2 = 1 offset.
Re bit 03:
Know-how protection cannot be deactivated, as p7766 is not entered in the OEM exception list (only the factory set-
ting is possible). This bit is only set if know-how protection is active (bit 1 = 1) and p7766 has not been entered in
the OEM exception list.
Re bit 04:
When know-how protection has been activated, the contents of the memory card (parameter and DCC data) can be
additionally protected against being used with other memory cards. This bit is only set if know-how protection is
active and p7765 = 1.
