1. RUN/STOP, normally found on pin 5 of the COP header, is not implemented on the PC7457. Connect pin 5 of the COP
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
6. Though defined as a No-Connect, it is a common and recommended practice to use pin 12 as an additional GND pin for
