Electrical Characteristics
4.7.6
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.MX53xD reference
manual to see which pins expose Tx and Rx pins; these ports are named TXCAN and RXCAN,
respectively.
