Figure 22-100. Message Buffer Cycle Counter Filter Registers (MBCCFRn)
This register contains message buffer configuration data for the transmission mode, the channel
assignment, and for the cycle counter filtering. For detailed information on cycle counter filtering, refer to
Section 22.6.7.1, Message Buffer Cycle Counter Filtering.

Description
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
Channel Assignment — These control bits define the channel assignment and control the receive and transmit
behavior of the message buffer according to Table 22-81.
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
Cycle Counter Filtering Mask — This field defines the filter mask for the cycle counter filtering.
Cycle Counter Filtering Value — This field defines the filter value for the cycle counter filtering.
