MSCAN Passive Error Handling by aborting the transmission

Hi All,

We are using the MSCAN in MPC5200B for my project CAN communication.
I am aborting the CAN message whenever there is a TX PASSIVE Error occurs. I
am creating the PASSIVE error by keeping CAN connection open.

My Question is:

The TX error counter values are never reset to ZERO though I did the CAN
initialization. Does MSCAN Error counter register values become ZERO after
every reset?if yes please let me know the complete RESET procedure.

Hence Error counters are not becoming ZERO CAN controller is marinating its
state in PASSIVE only so further unable to get the passive error interrupt
for the new message transmission by keeping the CAN connection open.

Thanks for your time.

Regards,
Venky
