These functions serve the users to select and receive a facultative message. The C0GMR register, the
C0LMAR register, and the C0LMBR register can perform masking to the standard ID and the extended ID
of 29 bits. The C0GMR register corresponds to slots 0 to 13, the C0LMAR register corresponds to slot 14,
and the C0LMBR register corresponds to slot 15. The masking function becomes valid to 11 bits or 29 bits
of a received ID according to the value in the corresponding slot of the C0IDR register upon acceptance
filtering operation. When the masking function is employed, it is possible to receive a certain range of IDs.
Figure 17.21 shows correspondence of the mask registers and slots, Figure 17.22 shows the acceptance
function.
When using the acceptance function, note the following points.
