13.5
The CAN-controller appears to the CPU as a
memory-mapped peripheral, guaranteeing the
independent operation of both parts.
13.5.1
The address area of the CAN-controller consists of the
Control Segment and the message buffers. The Control
Segment is programmed during an initialization down-load
in order to configure communication parameters (e.g. bit
timing). The communication over the CAN-bus is also
controlled via this segment by the CPU. A message which
is to be transmitted, must be written to the Transmit Buffer.

After a successful reception the CPU may read the
message from the Receive Buffer and then release it for
further use.
13.5.2
The exchange of status, control and command signals
between the CPU and the CAN-controller is performed in
the control segment. The layout of this segment is shown
in Fig.15. After an initial down-load, the contents of the
registers Acceptance Code, Acceptance Mask,
Bus Timing 0, Bus Timing 1 and Output Control should not
be changed. These registers may only be accessed when
the Reset Request bit in the Control Register is set HIGH
(see Tables 30, 31 and 32).
