System Design Information

1. The COP port and target board should be able to independently assert HRESET and TRST to the processor
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
5.This switch is included as a precaution for BSDL testing. The switch should be closed to position A during BSDL testing
6. Asserting SRESET causes a machine check interrupt to the e500 cores.
Notes:
signal integrity.
to position B.
to avoid accidentally asserting the TRST line. If BSDL testing is not being performed, this switch should be closed
