1. Populate this with a 10-Ω resistor for short circuit/current-limiting protection.
2. KEY location; pin 14 is not physically present on the COP header.
3. Use a AND gate with sufficient drive strength to drive two inputs.
5. This switch is included as a precaution for BSDL testing. The switch should be open during BSDL testing to avoid
6. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for
4. The COP port and target board should be able to independently assert HRESET and TRST to the processor in order
