How to use Safety port of MPC5604P MCU for the sencond FlexCAN purpose?

[tranhung]

Hi everyone;

I am using CAN communication features of  MPC5604P MCU. I would like to use two CAN to comunicate with other ECUs in automotive, but I dont know how to configure the safety port_0 (GPIO[14] and GPIO[15]) as the second FlexCAN.

Someone can suggest me to solve this problem?

Thanks you so much!

Hi, the only description I have found is following one:

1.5.21 Safety port (FlexCAN)
The MPC5604P MCU has a second CAN controller synthesized to run at high bit rates to be used as a safety port. The CAN
module of the safety port provides the following features:
• Identical to the FlexCAN module
• Bit rate as fast as 7.5 Mbit/s at 60 MHz CPU clock using direct connection between CAN modules (no physical transceiver required)
• 32 message buffers of up to 8 bytes data length
• Can be used as a second independent CAN module

Apparently the only difference is possibilty to run it at up 7.5 Mbit/s and without transceiver.
In other aspects it is normal FlexCAN and can be used the same way.
