Populate this with a 1 k Ω resistor for short-circuit/current-limiting protection. OVDD 10 k Ω PORESET1 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 TCK 3 3.This switch is included as a precaution for BSDL testing. The switch should be closed to position A during BSDL testing to position B. 10 k Ω 4 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.
