Hi, when working with smart cards and micro controllers you have five signals interfacing them: Clock, Reset, I/O line, Vcc and Ground. Clock and Reset...are they supposed to be quasi-bidirectional input only or Output only. What would be the right configuration for these signals? Thank you
Hi, Reset & clock needs to be output only . data line needs to be bidirectional line. You have to refer to iso 7816 standard for exact details. Also visit http://www.digicraftindia.com for more info on smart cards.
"Reset & clock needs to be output only." You need to clarify: Output from the micro, or output from the Smartcard...?
Output from the micro !!
