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.
