Specifications

The electrical characteristics are related to the CAN transceiver external to i.MX53xD such as MC33902

from Freescale.The i.MX53xD has two CAN modules available for systems design. Tx and Rx ports for

both modules are multiplexed with other I/O pins. See the IOMUXC chapter of the i.MX53 Reference

Manual to see which pins expose Tx and Rx pins; these ports are named TXCAN and RXCAN,

respectively.
