The following paragraphs briefly describe the major features of the
ECAN1000HR. A more detailed discussion in included in Chapter 4
(Hardware description) and in Chapter 5 (Board operation and program-
ming). The board setup is described in Chapter 2 (Board Settings). A full
description of the Philips SJA1000 CAN-controller is included in Chapter
5 (Board operation and programming).
CAN bus controller
The ECAN1000HR CAN bus interface is implemented using the Philips
SJA1000 controller. This controller supports CAN Specification 2.0. This
versatile chip supports standard and extended Data and Remote frames;
a Programmable Global Message Identifier Mask; 15 message objects of
8-byte Data Length and a Programmable Bit Rate. This fully integrated
chip supports all the functionality of the CAN bus protocol. The internal 64
byte receive FIFO is ideal for block mode data transfer from the CAN
controller chip.
