8.12 Communications Peripherals

Note

For the actual number of each peripheral on a specific device, see Table 6-1.

8.12.1 Controller Area Network (CAN)

The CAN module performs CAN protocol communication according to ISO 11898-1 (identical to Bosch® CAN

protocol specification 2.0 A, B). The bit rate can be programmed to values up to 1 Mbps. A CAN transceiver chip

is required for the connection to the physical layer (CAN bus).

For communication on a CAN network, individual message objects can be configured. The message objects and

identifier masks are stored in the Message RAM.

All functions concerning the handling of messages are implemented in the message handler. These functions

are: acceptance filtering; the transfer of messages between the CAN Core and the Message RAM; and the

handling of transmission requests.

The register set of the CAN may be accessed directly by the CPU through the module interface. These registers

are used to control and configure the CAN core and the message handler, and to access the message RAM.

The CAN module implements the following features:

• Complies with ISO11898-1 (Bosch® CAN protocol specification 2.0 A and B)

• Bit rates up to 1 Mbps

• Multiple clock sources

• 32 message objects (“message objects” are also referred to as “mailboxes” in this document; the two terms

are used interchangeably), each with the following properties:

– Configurable as receive or transmit

– Configurable with standard (11-bit) or extended (29-bit) identifier

– Supports programmable identifier receive mask

– Supports data and remote frames

– Holds 0 to 8 bytes of data

– Parity-checked configuration and data RAM

• Individual identifier mask for each message object

• Programmable FIFO mode for message objects

• Programmable loop-back modes for self-test operation

• Suspend mode for debug support

• Software module reset

• Automatic bus-on, after bus-off state by a programmable 32-bit timer

• Message-RAM parity-check mechanism

• Two interrupt lines

Note

For a CAN bit clock of 200 MHz, the smallest bit rate possible is 7.8125 kbps.

Note

Depending on the timing settings used, the accuracy of the on-chip zero-pin oscillator (specified in the

data manual) may not meet the requirements of the CAN protocol. In this situation, an external clock

source must be used.

Figure 8-60 shows the CAN block diagram.
