JTAG Connection
Mechanical Description of the 20-pin Debug Cable
This is a standard 20 pin double row connector (pin-to-pin spacing: 0.100 in.).
We strongly recommend to use a connector on your target with housing and having a center polarization
(e.g. AMP: 2-827745-0). A connection the other way around indeed causes damage to the output driver of
the debugger.
