17.13.14 msCAN12 Identifier Mask Registers (CIDMR0–7)
The identifier mask register specifies which of the corresponding bits in
the identifier acceptance register are relevant for acceptance filtering. To
receive standard identifiers in 32 bit filter mode it is required to program
the last three bits (AM2–AM0) in the mask registers CIDMR1 and
CIDMR5 to ‘don’t care’. To receive standard identifiers in 16 bit filter
mode it is required to program the last three bits (AM2–AM0) in the mask
registers CIDMR1, CIDMR3, CIDMR5 and CIDMR7 to ‘don’t care’.
