Notice: If there is no OA application, then it is not possible to access an index.
Note: The parameter is only for internal Siemens diagnostics.
Description: Displays the status for the write protection and know-how protection.
Note: KHP: Know-How Protection
Re bit 00:
Write protection can be activated/deactivated via p7761 on the Control Unit.
Re bit 01:
The know-how protection can be activated by entering a password (p7766 ... p7768).
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
setting 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/Control Units. This bit is only set if know-how
protection is active and p7765 bit 00 is set.
Re bit 05:
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 in p7765 bit 01 is set and not bit 00.
Re bit 06:
When know-how protection is activated, the drive data can be traced using the device trace function. This bit is only
set if know-how protection is active and in p7765.2 is set.
Description: Sets the number of parameters for the OEM exception list (p7764[0...n]).
p7764[0...n], with n = p7763 - 1
