_9111_EDO 
@ Description 
There are 4 extended digital output channels on PCI_9111. This function 
is used to write data to extended digital output port. The extended digital 
output channels can be set as three modes (refer to section 6.2.10); 
however, the output EDO value can be put on the EDO pins only when the 
EDO mode is set as EDO_OUT_CHN. Therefore, the program should call 
_9111_Set_EDO_Function (refer to section 6.2.10) to set EDO mode as 
EDO_OUT_EDO before writing data to EDO channels.
