Figure 8-14. JTAG Interface Connection
Notes:
The COP header shown in
points, register and memory examination/modification and other standard debugger features are
possible through this interface – and can be as inexpensive as an unpopulated footprint for a
header to be added when needed.

1. RUN/STOP, normally found on pin 5 of the COP header, is not implemented on the PC755.
2. Key location; pin 14 is not physically present on the COP header.
3. Component not populated. Populate only if debug tool does not drive QACK.
4. Populate only if debug tool uses an open-drain type output and does not actively deassert
5. If the JTAG interface is implemented, connect HRESET from the target source to TRST from

mented, connect HRESET from the target source to TRST of the part through a 0Ω isolation
resistor.
