bits ID24 and ID22 are 1, are to be stored in message buffer 14. The procedure for this example is shown below.
For some message buffers that are used for reception, whether one of four global reception masks is applied can
Load resulting from comparing message identifiers is reduced by masking some bits, and, as a result, some
By using the mask function, the identifier of a message received from the CAN bus can be compared with the
While the mask function is in effect, an identifier bit that is defined to be 1 by a mask in the received message is not
However, this comparison is performed for any bit whose value is defined as 0 by the mask.
For example, let us assume that all messages that have a standard-format ID, in which bits ID27 to ID25 are 0 and
