System Design Information
Figure 24. JTAG Interface Connection
There is no standardized way to number the COP header shown in
Figure 24
; consequently, many different pin
numbers have been observed from emulator vendors. Some are numbered top-to-bottom then left-to-right, while

Notes:
1. RUN/STOP, normally found on pin 5 of the COP header, is not implemented on the MPC755. Connect pin 5 of the COP header
to OV
DD
with a 10-k
pull-up resistor.
2. Key location; pin 14 is not physically present on the COP header.
3. Component not populated. Populate only if debug tool does not drive QACK.
4. Populate only if debug tool uses an open-drain type output and does not actively deassert QACK.
5. If the JTAG interface is implemented, connect HRESET from the target source to TRST from the COP header though 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-
isolation reisistor.
