Freescale Semiconductor
Physical Pin Out
COP Connector
Notes:
1. RUN/STOP, normally found on pin 5 of the COP header, is not implemented on the MPC755. Connect
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
6. The COP port and target board should be able to independently assert HRESET and TRST to the
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-Ω isolation resistor.
