Hello:
I use the MPC5604C chip to develop gateway products. The reference manual describes that each CAN controller only supports 64 HOHs (6 CAN controllers in total, 6*64=384). My question is can these 384 HOHs be shared? Because we currently use 5 CAN controllers, but one of controllers needs 74 HOH (in FULL mode), how can I do it, looking forward to the reply.

Hi,

there is no possibility of sharing MBs between modules.

hi,

Should I allocate some messages to receive or send in BASIC mode? As a CAN gateway, will it be very suitable? Any good suggestions?

I did a test and found that the configuration of HOH exceeds 64, EB will prompt an error, what should I do?
