Configuration of subdevices

Hello!
I am working with a PCI DIO National Instruments card under Linux. I want to 
use a single data bus, in order first to write in 12 bits, and then to read 
from the same 12 bits. I wanted to ask how could I configure the subdevice of 
12 bits as a bidirectional subdevice. Also how do I use the configuration 
instruction (INSN_CONFIG)? 
Thanks a lot!
