The board uses the SJA-1000 chip. If this chip is put into PeliCAN mode, it uses 128 I/O addresses instead of 32.
My question is, are those additional addresses accessible? If so, are there any limitations involved in configuring the card in this case?
Also, is there any way to disable one of the CAN ports, so that it doesn't take up any I/O space?
As you could see in the Description on page 11, the card always use PORT Adresses, so you could not configure a CAN channel in the way that it will not be mapped to a CAN Controller.
For Detail how the CAN Controller will be available via the IO Ports, please take a closer look into our LINUX drivers. All Information is part of this driver. The Pelican Mode do not need more Register - all could be handle with this I/O Address Range.
