Figure 18-5. 8-bit Maskable Acceptance Filters
The identifier acceptance registers (CIDAR0–7) define the acceptable
patterns of the standard or extended identifier (ID10–ID0 or ID28–ID0).
Any of these bits can be marked don’t care in the identifier mask
registers (CIDMR0–7).
A filter hit is indicated to the application software by a set RXF (receive
buffer full flag, see msCAN12 Receiver Flag Register (CRFLG)) and
