Section 15 Controller Area Network (HCAN)
15.3.18 Message Control (MC15 to MC0)
The message control register sets consist of eight 8-bit registers for one mailbox. The HCAN has
16 sets of these registers. Because message control registers are in RAM, their initial values after
power-on are undefined. Be sure to initialize them by writing 1 or 0. Figure 15.2 shows the
register names for each mailbox.
The setting of message control registers are shown in the following. Figures 15.3 and 15.4 show
the correspondence between the identifiers and register bit names.
