25.4 Functional Overview
The FlexCAN module is flexible in that each one of its 16 message buffers (MBs) can be
assigned either as a transmit buffer or a receive buffer. Each MB, which is up to 8 bytes
long, is also assigned an interrupt flag bit that indicates successful completion of either
transmission or reception.
Note that for both processes, the first CPU action in preparing
a MB should be to deactivate it by setting its code field to the
proper value. This requirement is mandatory to assure proper
operation.
