DMA-logic controlled via bit CANADR.7 (see Section 13.5.17).
Reserved.
Auto Address Increment mode controlled via bit CANADR.5 (see Section 13.5.16).
The five least significant bits CANADR.4 to CANADR.0 define the address of one of the
CAN-controller internal registers to be accessed via CANDAT. For instance, after an
external hardware (e.g. power-on) reset CANADR contains the value 64H, and hence
the CPU accesses (read/write) the Acceptance Code register of the CAN-controller, via
the SFR CANDAT.

The SFR CANDAT appears as a port to the CAN-controller internal register (memory
location) being selected by CANADR. Reading or writing CANDAT is effectively an
access to that CAN-controller internal register, which is selected by CANADR.
