to fully control the processor as shown here.
1. The COP port and target board should be able to independently assert HRESET and TRST to the processor
signal integrity.

5.This switch is included as a precaution for BSDL testing. The switch should be closed to position A during BSDL testing
to position B.

6. Asserting SRESET causes a machine check interrupt to the e500 cores.
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
to avoid accidentally asserting the TRST line. If BSDL testing is not being performed, this switch should be closed
