Hi

I am trying to generate 6 chipselect from master uno by using 6 i/o , as we all know only one chipselect is there so i am using i/o pins,initially condition all 6 are set to HIGH ,then one i/o should go low and high then only next i/o should go low and high like that all remaning 4 should go low and high one after other,the problem was first is going low and high but remaning all are not going low there are in the high state itself(initial condition).
can any one tell the reason for it.

How do you know this?
Are you looking at the CS pin on a scope?
