CAN: Do GUI options affect AMR and ACR register?
I use Full mailboxes with the FIFO functionality and I want to have 4 FIFOs in total. Consequently, I link receive mailboxes 0 to 3, 4 to 7, 8 to 11 and 12 to 15 together. Then I set the following IDs for the four groups: 0x10B, 0x30B, 0x50B, 0x70B. IDE is 0 since I want to communicate with 11-bit-COB-IDs. Every configuration until now is done with the GUI.
If I run my program and print the contents of my ACR/AMR register to the LCD they do not match my GUI configurations (e.g. the IDE bit is set in the ACR). Why is that? Further, although they are linked together, mailboxes of the same group seem to have slightly different ACR/AMR configurations. Do they simply not apply in the FIFO case or what am I doing wrong?
Thanks in advance!
