JTAG Interface Connection
Notes:
1. RUN/STOP, normally found on pin 5 of the COP header, is not implemented on the PC755. Connect pin 5 of the COP
header to OV
DD
with a 10 k
pull-up resistor.
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 QACK.
5. If the JTAG interface is implemented, connect HRESET from the target source to TRST from the COP header though an
AND gate to TRST of the part. If the JTAG interface is not implemented, connect HRESET fromthe target source to TRST of
the part through a 0
isolation resistor.
