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.

6. Asserting SRESET causes a machine check interrupt to the e500 core.
