Hardware Design Considerations

2. Populate this with a 10 Ω resistor for short-circuit/current-limiting protection.
3. The KEY location (pin 14) is not physically present on the COP header.
4. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for improved
6. Asserting HRESET causes a hard reset on the device.
1. The COP port and target board must be able to independently assert PORESET and TRST to the processor
5.This switch is included as a precaution for BSDL testing. The switch must be closed to position A during BSDL testing
Notes:
signal integrity.
to avoid accidentally asserting the TRST line. If BSDL testing is not being performed, this switch must be closed
to position B.
