Differences between Fujitsu mb96f346 and mb90f340 on CAN Bus

The drivers are basically the same during use. Note the following differences:

1. The Bosch CAN used in mb96f346 is more similar to the can structure of other brands. If any questions are found during the test, refer to other single-chip microcomputer, such as stm32.

Mb90f342 is based on Fujitsu's can design. Its structure is slightly different from that of Bosch CAN.

2. Receive filter options: mb90 series can has four options, 0 full bit comparison 1 full bit mask 2 Use comparator amr0 3 Use comparator amr1, while comparator amr0, 1 can be set

The mb96 series can has two options: 0 uses the comparator AMR 1 full bit mask, and the comparator is only one Amr.

3. The order of the corresponding bits of the 29-bit comparator is also different from that of the two single-chip computers. If the mb90 series uses a comparator, pay attention to the position of the mask BITs during the migration to the mb96, it may need to be adjusted.

4. The mb96 series share 32 can-buffers for two channels. The mb90 series uses 16 can-buffer for each channel.

The above situation may cause problems during the modification process. I would like to leave a message to remind you.
