I want to use individual masking functionality of FlexCAN by setup a mask to received CAN Message.
My setup is the following:
- use MB1 as receive message box
- IDAM bit = Format A
- IRMQ bit = 1 (individual masking is enabled and FIFO is not used)
- RXIMR1 = 0x00000700 (I want to receive all IDs between 0x300 and 0x3FF)
- ID = 0x300 therfore in MB.ID it is 0xC000000
I verified that the RXIMR1 register is written correctly in FreezeMode
I also verified that MB.ID is also written correctly.
Why do I get all CAN ID´s with this Setup and the defined mask (0x700) has no effect ?
Is there any additional configuration which I missed ?
Thanks for your help.
