Hi to all,

I need help on 2 track card reader.
Each track has clock, data and card insert pins
The data is valid when the clock is low.
I am thinking to setup interrupt on falling edge
To capture data line this is for track 1 only
If I use second interrupt pin to do that for track 2
I do not think it will work because clock and data on
Both tracks starts at the same time so guess I need to capture
The data parallel in this case I have to read the port
Every cycle. Does any one have any idea implementing it better
Way. Any help will appreciate.

Andre
