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.</P><P>Tapping this pin to CAN and I2C , a good design?. I am sure No. Help me how to use CAN and I2C\</P><P>Thanks</P><P>Regards,</P><P>Gilbert</P></BODY></HTML> Thu, 09 Dec 2010 14:59:28 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF52277-Doubt/m-p/168453#M6044 Gilbert 2010-12-09T14:59:28Z Re: MCF52277 Doubt https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF52277-Doubt/m-p/168454#M6045 <HTML><HEAD></HEAD><BODY><P>it seems there are another pins have i2c function &nbsp;in mcf52277, except for those multiplex with can</P><P>&nbsp;</P><P>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.</P><P>&nbsp;</P></BODY></HTML> Fri, 10 Dec 2010 15:12:00 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/MCF52277-Doubt/m-p/168454#M6045 bluehacker 2010-12-10T15:12:00Z
