My customer want to ingore CANFD in bus. Whether the FEND = 0 can be implemented?
Or if S32K1 has other memory can be set to ignore CANFD?(Ensure that the bus can communiate properly)
Or if any other MCU has this capability?
PS: CAN transceivers CAN be seleted with or without CANFD
Solved! Go to Solution.
Hi @jingfang
Configuring MCR[FDEN] with a bit 0 lets you have receptions and transmissions in CAN format, but before you do that you have to enter to Freeze mode which you can find its configuration on page 1797 of the S32K1xx Series Reference Manual. If you don’t activate this mode you are not to be able to manipulate FDEN.

Thanks a lot~
If I activate Freeze mode and manipulate FDEN.
Exit the Freeze mode, will the FDEN state not change?
Hi @jingfang
When you come out of Freeze Mode, all settings you have made in it will remain as you did.
