Figure 23.1 shows a block diagram of the CAN module for CAN0 and CAN1. Figure 23.2 shows CANi message slot
buffer (i = 0, 1) and CANi message slot (message slot) j (j = 0 to 15). Table 23.2 lists pin settings of the CAN module.
The CPU cannot access the message slot directly. Allocate necessary message slot j to the CANi message slot buffer 0
or 1 and access the message slot j via the allocated address. The CiSBS register selects the message slot j to be
allocated. The message slot buffer and message slot consist of 16 bytes shown in Figure 23.2.
