MCF52277 Doubt

[Gilbert]

Hi All. I am using MCF52277 for my design. I need CAN and I2C. But in this device both are multiplexed in the same pin. How can I use bith CAN and I2C. My primary communication is CAN and it can happen any time from the peripherals. But I2C is time triggered on and will happen once in 5 minutes or so.

Tapping this pin to CAN and I2C , a good design?. I am sure No. Help me how to use CAN and I2C\

Thanks

Regards,

Gilbert

it seems there are another pins have i2c function  in mcf52277, except for those multiplex with can

by the way, I also do 52277 board, but I find it has too many multiplex pins, which is a very bad design, currently, I am going to quit the project, and select new mpu to do it.
