COP Connector Diagram
Notes:
1. RUN/STOP, normally found on pin 5 of the COP header, is not implemented on the
PC7410. 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 from the target source to TRST of the
part through a 0
isolation resistor
.
6. The COP port and target board should be able to independently assert HRESET and
TRST to the processor in order to fully control the processor as shown above.
