The final value programmed into the CANBIT register = 0x34F1.
19.4 Register Map
Table 19-5 on page 1375 lists the registers. All addresses given are relative to the CAN base address
of:
■ CAN0: 0x4004.0000
■ CAN1: 0x4004.1000
Note that the CAN controller clock must be enabled before the registers can be programmed (see
page 395). There must be a delay of 3 system clocks after the CAN module clock is enabled before
any CAN module registers are accessed.
