I wonder if I am understanding the setting of identifier acceptance filter for MSCAN.
I have a MC9S08DZ128 and I would like to set 4 filters of 16bits.
How should I think to set mask and code ?
I have made 4 different codes with their mask : for example :
I would like to filter ID of 0x1A1 :
CANIDAR0 = 0x34;
CANIDAR1 = 0x20;
CANIDMR1 = 0x07;
It works fine. But when I want to set another filter (CANIDAR2 and CANIDAR3 with CANIDMR2 and CANIDMR3), it doesn't work.
How do filters work ? I should I do to set 4 filters ?
Thank you in advance for your answers.
