Hi Biser-san,
Thank you for your reply.
I think that IFxMSK register is masked with a received message.
However, I don't know how IFxARB register work when receiving message.
That isn't described on TRM, so could you tell me more details?
It will be very helpful for me if you show me the calculation of the logical operation.

Hi, Schuyler-san,
Thank you for your reply.
> Is there an OS being used and does it have a DCAN driver?
No, our customer uses StraterWare for AM335x.
I need to know how IFxARB and IFxMSK registers affect the acceptance mechanism.
Otherwise, I wouldn't be able to convince him.

Hi Deepa-san,

Hi Deepa-san,
Case1)
ARB : 0x1FFFFFFF
MSK : 0x1XFFFFXF
Case2)
ARB : 0x10FFFF0F
MSK : 0x1XFFFFXF
What is the difference in acceptable identifier between above case1 and case2?
