Hello,

I' using spc56EL70L5

I'm trying to define several CAN acceptance filters. Let's say I want to receive ids 0x100 to 0x1FF and 0x400 to 0x4FF, only regulars. I config as following:

BCC = 1

RXFIFO.IDTABLE

[

0

] =

0x08000000

RXIMR

[

0

] =

0xf8000000

RXFIFO.IDTABLE

[

1

] =

0x20000000

RXIMR

[

1

] =

0xf8000000

MCR = 0x2003001F

The second filter (

IDTABLE

[

1

] and 

RXIMR

[

1

]) has no effect and only ids 0x100 to 0x1FF are received.

I don't understand how to use the 8 filters.

Thanks
