18.2 Introduction
The MC68HC912DT128A has three identical msCAN12 modules,
identified as CAN0, CAN1 and CAN2. The MC68HC912DG128A has
two: CAN0 and CAN1. The information to follow describes one msCAN
unless specifically noted and register locations specifically relate to
CAN0. CAN1 registers are located 512 bytes from CAN0, and on the
MC68HC912DT128A, CAN2 registers are located 256 bytes from
CAN0.
