in order to fully control the processor as shown here.
1. The Aurora port and target board should be able to independently assert PORESET and TRST to the processor

3.This switch is included as a precaution for BSDL testing. The switch should be closed to position A during BSDL testing

4. Asserting HRESET causes a hard reset on the device. HRESET is not used by the Aurora 22 pin connector.
to avoid accidentally asserting the TRST line. If BSDL testing is not being performed, this switch should be closed
