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