13.3.19 Message Data (MD0 to MD15)
The message data register sets consist of eight 8-bit registers for one mailbox. The HCAN has 16
sets of these registers. Because message data registers are in RAM, their initial values after power-
on are undefined. Be sure to initialize them by writing 0 or 1. Figure 13.5 shows the register
names for each mailbox.
