Flexible I/O Setting

To use the trigger interrupt from flexible I/O, the switches must be in the positions:

(D2,D1,D0)    Latching Signal
    0         Input 0
    1         Input 1
    2         Input 2 
    3         Input 3
    4         External Strobe
    5         OR(Input 0,Input 1,Input 2,Input 3)
    6         OR(Input 0,Input 1,Input 2,Input 3,External Strobe)
    7         No latching Signal

Note: open swtich(OFF) is a "1", closed switch(ON) is a "0"

In main board of FlexIO, there is a switch to choose the priority of interrupt.
