Populate this with a 10 Ω resistor for short-circuit/current-limiting protection. NC OVDD 10 k Ω 10 k Ω HRESET1 in order to fully control the processor as shown here. 4. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for 1. The COP port and target board should be able to independently assert HRESET and TRST to the processor improved signal integrity. TCK 4 5 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. 10 k Ω 6 6. Asserting SRESET causes a machine check interrupt to the e500 core. |
