NOTE
If at least one message buffer assigned to a certain slot is assigned to both
channels, then all message buffers assigned to this slot have to be assigned
to both channels. Otherwise, the message buffer configuration is illegal and
the result of the message buffer search is not defined.

Field
Description
MTM
Message Buffer Transmission Mode. This control bit applies only to transmit message buffers and defines the
transmission mode.
0 Event transmission mode
1 State transmission mode
CHA
CHB
Channel Assignment. These control bits define the channel assignment and control the receive and transmit
behavior of the message buffer according to

CCFE
Cycle Counter Filtering Enable. This control bit is used to enable and disable the cycle counter filtering.
0 Cycle counter filtering disabled
1 Cycle counter filtering enabled
CCFMSK
Cycle Counter Filtering Mask. This field defines the filter mask for the cycle counter filtering.
CCFVAL
Cycle Counter Filtering Value. This field defines the filter value for the cycle counter filtering.
