[pci] GENERAL PURPOSE I/O

       I AM USING INTEL 9030 PLX CHIP TO INTERFACE WITH DPRAM 
WHICH INTERN WILL COMMUNICATE WITH CODEC. IN 9030 SOME GENERAL 
PURPOSE I/O PINS ARE GIVEN WHICH CAN BE CONFIGURED AS INPUT OR 
OUTPUT AND THE LOCAL DEVICE CAN READ OR WRITE SINGLE BIT ON THAT 
PIN BUT I DONT KNOW HOW PCI WILL READ OR WRITE TO THAT PIN. IF 
ANYBODY KNOWS THE ANSWER THEN PLZ. MAIL ME SINCE I HAVE DIFFICULTY 
IN WRITTING THE DEVICE DRIVER. ACTULLY I AM INTERFACING IVRS 
SYSTEM WITH PCI.

     THANKS .
