Debug Port Connector
The debug connector consists of a 5.5 inch ribbon cable with the appropriate debug
connector attached. The ribbon cable has a red stripe down one side to indicate the
location of pin 1.
NOTE
The OnCE connector is equipped with a removable plug in pin 8. This follows
the keying convention for the OnCE header (pin 8 should be removed). This
plug is removable, in case the target being connected to it does not come with
pin 8 removed.

Electrical Characteristics
The USB TAP was designed to affect the target processor and target electrical
characteristics as little as possible. Care, however, should be taken in designing the target
to accommodate the small signal delays associated with any in-circuit emulator or other
test equipment.
The USB TAP automatically supports target signal levels from 1.8V to 3.3V.
