#22627 - RE: I/O lines in smartcard application |
resolved!
it turns out that the reset line on my card is a transition high->low, when for the 8051 uC it should be low->high and then low again! then the rst line remains high on my card, thus putting the device in a undefined reset state!! so I have to invert the state of the pin, how could I do it? I need something like a NOT port regards, teo. |
