MTTCAN can be configured as mCAN on MPC5777M?

TTCAN is not compatible with mCan, Can I configure MTTCAN module as mCAN mode？

Hi,

if you want to use M_TTCAN module for normal CAN communication the same way as for M_CAN then yes, you can. The M_TTCAN performs communication according to ISO 11898-1 (identical to Bosch CAN protocol specification 2.0 part A,B). But M_TTCAN is implemented in a lower IP revision compared to M_CAN and therefore the supported CAN FD features are different, i.e. M_TTCAN doesn’t have full FD capability, maximum payload of 8-bytes is supported.

BR, Petr

I just try it, don't config any time-triggered registers, it can communicate with mcan, thank you.

thanks, could you tell me how to configure the regs, because there are many registers of time-triggered. I only keep TTOCF[OM] = 0. Is there anything else to do?
