CAN Controller (C505C and C505CA only)
The on-chip CAN controller, compliant to version 2.0B, is the functional heart which provides all
resources that are required to run the standard CAN protocol (11-bit identifiers) as well as the
extended CAN protocol (29-bit identifiers). It provides a sophisticated object layer to relieve the
CPU of as much overhead as possible when controlling many different message objects (up to 15).
This includes bus arbitration, resending of garbled messages, error handling, interrupt generation,
etc. In order to implement the physical layer, external components have to be connected to the
C505.
The internal bus interface connects the on-chip CAN controller to the internal bus of the
microcontroller. The registers and data locations of the CAN interface are mapped to a specific
256 byte wide address range of the external data memory area (F700H to F7FFH) and can be
accessed using MOVX instructions.
Figure 15
shows a block diagram of the on-chip CAN
controller.
