Dear all:

      I use LPC2292’s CAN , But I can’t use it’s filter properly.

      2292 has two cans, I let can1 send data to can2. If I disable the
filter,the data is properly received, But if I enable the filter, I see that
the CANRFS,CANRID,CANRDA and CANRDB has received the data properly, but the
RBS bit is not set to ‘1’. I set the filter ram as the datasheet say, and
I have set the SFF_sa,SFF_GRP_sa,EFF_sa,EFF_GRP_sa and EndOfTable, I have
set AFMR to 0x00 and filled the unused ram to 0xf7fff7ff. I don’t know way.
Is there anyother thing I should do? 

      Thanks very much.
