- Enable generic 8255 support.
+ Enable support for 8255 digital I/O as a standalone driver.
You should enable compilation this driver if you plan to use a board
- that has an 8255 chip. For multifunction boards, the main driver will
- configure the 8255 subdevice automatically.
+ that has an 8255 chip at a known I/O base address and there are no
+ other Comedi drivers for the board.
- Note that most PCI based 8255 boards use the 8255_pci driver as a
- wrapper around this driver.
+ Note that Comedi drivers for most multi-function boards incorporating
+ an 8255 chip use the 'comedi_8255' module. Most PCI-based 8255
+ boards use the 8255_pci driver as a wrapper around the 'comedi_8255'
+ module.
