CIDAR3
On reception each message is written into the background receive
buffer. The CPU is only signalled to read the message, however, if it
passes the criteria in the identifier acceptance and identifier mask
registers (accepted); otherwise, the message will be overwritten by the
next message (dropped).
The acceptance registers of the MSCAN08 are applied on the IDR0 to
IDR3 registers of incoming messages in a bit by bit manner.
For extended identifiers, all four acceptance and mask registers are
applied. For standard identifiers only the first two (CIDMR0/1 and
CIDAR0/1) are applied.
