Section 13 Controller Area Network (HCAN)
13.3.18 Message Control (MC0 to MC15)
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 0 or 1. Figure 13.2 shows the
register names for each mailbox.
The setting of message control registers are shown below. Figures 13.3 and 13.4 show the
correspondence between the identifiers and register bit names.
