Figure 22.1 shows a block diagram of the CAN module. Figure 22.2 shows CANi message slot buffer (the
message slot buffer) (i=0,1) and CANi message slot (the message slot) j (j=0 to 15). Table 22.2 lists pin
settings of the CAN module.
The message slot cannot be accessed directly from the CPU. Allocate the message slot j to be used to the
message slot buffer 0 or 1. The message slot j is accessed via the message slot buffer address. The
CiSBS register selects the message slot j to be allocated. Figure 22.2 shows the 16-byte message slot
buffer and message slot.
