Re: Jtag

Hi,
JTAG (joint Test Acc Grp) is a standard for debugging embedded processors. They are used normally with emulators where control points are communicated. You may set breakpoints/singlestep ... .

Parallel port is for data trnasfer only. When the processor wants to communicate anything to outside world it uses either serial or parallel ports.

hope this helps,
