6.7 Configuration of the SJA1000

Refer to the SJA1000 data sheet for all details on how to program the SJA1000. You need to
know the following:



RX1 is connected to ground.



TX1 is not connected.



CLKO is not connected.



Setting the OCR register to 0xDA is a good idea. This means “normal output mode”,
push-pull and the correct polarity.



In the CDR register, you should set CBP to 1. You will probably also want to set the
clock divider value to 0 (meaning divide-by-2), the Pelican bit, and the clock-off bit
(you have no need for CLKOUT anyway.)

The only way to find out how many SJA1000 a PCIEcan card has, is to try to access them
one after the other.
