The message slot j (j = 0 to 15), selected with bits SBS03 to SBS00, is allocated to the CANi message slot
buffer 0. The message slot j can be accessed via the allocated addresses (CAN0: addresses 01E0h to 01EFh;
CAN1: 0260h to 026Fh).
The message slot j, selected with bits SBS13 to SBS10, is allocated to the CANi message slot buffer 1. The
message slot j can be accessed via the allocated addresses (CAN0: addresses 01F0h to 01FFh; CAN1: 0270h to
027Fh).
NOTES:
1. 16 CANi message slots are provided. Each message slot can be selected as a transmit message slot or receive message slot.
2. The value is obtained by setting the SLEEP bit in the CiSLPR register to 1 (sleep mode exited) after reset and supplying the
clock to the CAN module.
