The user has the choice to program one of the following two options for filtering the M5
and M6 bits changes except FEBE or CRC bits:
• Same validation algorithm as programmed for M4 bits (MFILT.M56= ’X0’ = default
• On Change (MFILT.M56= ’X1’)
Note: The issue of the corresponding Monitor messages is delayed for 12 ms (= U-
Filter Setting via Pin AUTO and Pin CRCON
Once after a pin reset, the settings of both AUTO and CRCON pins are evaluated and
the MFILT register is preset as follows. The setting of pin AUTO determines the
operational mode of the Embedded Operations Channel:
• Pin AUTO set to ’1’ selects automode for all line ports and corresponds to the following
• Pin AUTO set to ’0’ selects transparent mode for all line ports and corresponds to the
Via pin CRCON the CRC filter mode for the overhead bits can be activated or
deactivated (See
• Pin CRCON set to ’1’ enables the CRC mode for all line ports and corresponds to the
• Pin CRCON set to ’0’ disables the CRC mode for all line ports and corresponds to the
Note that the pin setting is only evaluated once after pin reset. This fact allows to
reprogram the verification modes later on by a MON-12 command. The MFILT register
setting is evaluated each time the U-transceiver enters the DEACTIVATED state.
