4. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for
improved signal integrity.

5. This switch is included as a precaution for BSDL testing. The switch should be open during BSDL testing to avoid
accidentally asserting the TRST line. If BSDL testing is not being performed, this switch should be closed or removed.

2. Populate this with a 10
Ω resistor for short-circuit/current-limiting protection.
1. 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 here.
