Wrong information in Hardware Reference

Hi Thomas,

Your understanding is correct. The meaning of bit is reversed. We are aware of this mistake. Hopefully it will be corrected in next revision of manual.

Thanks,

Prashant

Ok, thanks!

But maybe I've found a second issue. Where can I find some information about the register where to write the CAN-Message ID?

The 11-bit BaseID should be set in CAN_MBxx_ID1[12:2] field.

The 18-bit Extended ID should be specied in CAN_MBxx_ID1[1:0] and CAN_MBxx_ID0[15:0] fields. The upper 2-bits in ID1 register and remaining 16-bits in ID0 register.

This is same settings as in previous Blackfin processor's CAN module.

Thanks! I already thought so. I was just wondering about the text in the manual (page 21-82:

     "Mailbox ID 1 Register

     The CAN_MBnn_ID1 register and CAN_MBnn_ID0 register manage acceptance mask operations. For      information about acceptance mask operation, see the Receive Operation section."

That text is also incorrect, and we will make sure it also gets addressed in the next revision of the manual.  The supporting text for the ID0/1 register pair should be describing that these registers define the function of the mailbox, whether it is a specific message ID or a group of message IDs.
