When the setting value of the ID filter is other than 00000000H, a message matching the bit specified as OFF by the ID filter
from the setting value of CAN-ID will be received. Comparison is not made for the bit specified as ON.
Ex.
When the CAN-ID is 40H and 0FH is specified by the ID filter, a message with a CAN-ID in the range 40H to 4FH is received.
