I use MC9S08DZ60 and I must make a CAN application, but I am not able to do the can filter.
I set the CANIDAC register fo two filter of 32 bit, the CANIDAR0/3 registers with my ID that I want to filter and the CANIDMR0/3 with the mask, how it is written on data sheets, but it does not function
I write the example that I am doing
CANIDAC=0x00 obviously written with its procedure
With this mask I want to applicate the filter only at the four initial byte and the other are do not care.
Can someone help me? Does someone know what I make the mistake?
