Notes:
1. QACK is an output and is not required at the COP header for emulation.
2. RUN/STOP normally on pin 5 of the COP header is not implemented on the MPC8241.
Connect pin 5 of the COP header to OVDD with a 1- kΩ pull-up resistor.
3. CKSTP_OUT normally on pin 15 of the COP header is not implemented on the MPC8241.
Connect pin 15 of the COP header to OVDD with a 10-kΩ pull-up resistor.
4. Pin 14 is not physically present on the COP header.

7. The COP port and target board should be able to independently assert HRESET and TRST to
.
the processor to fully control the processor as shown.
8. If the JTAG interface is implemented, connect HRESET from the target source to TRST from the COP
header through an AND gate to TRST of the part. If the JTAG interface is not implemented, connect
HRESET from the target source to TRST of the part through a 0-
Ω isolation resistor.
