The 5485 Reference manual (MCF5485RM.pdf) mentions in section 1.4.6.7 that the message buffers for the two 16 messages CAN controllers can be configured as a single 32 message buffer CAN network.
 
However in section 21 of the same manual it really doesn't describe how to set this up.  The MAXMB field of the CANMCR register only allows 0 - 15.
 
Is there a description on how to configure for 32 message buffers?
