18.5 Internal Registers of CAN Controller

18.5.1 CAN module register and message buffer addresses

In this chapter all register and message buffer addresses are defined as address offsets to different
base addresses.
Since all registers are accessed via the programmable peripheral area the bottom address is defined by
the BPC register (refer to <Peripheral-IO-Reference> or to <Peripheral-IO-Reference-2>).
The addresses given in the following tables are offsets to the programmable peripheral area base
address PBA.
The setting of BPC is fixed to 8FFB
address
PBA = 03FE C000
Table 18-17 lists all base addresses used throughout this chapter.

In the following <CnRBaseAddr> respectively <CnMBaseAddr> are used for the base address names
for CAN channel n.
