PCI Reference Voltage—LVDD
The MPC8240 PCI reference voltage (LVDD) pins should be connected to 3.3 ±0.3 V power supply if
interfacing the MPC8240 into a 3.3-V PCI bus system. Similarly, the LVDD pins should be connected to
5.0 ±5% V power supply if interfacing the MPC8240 into a 5-V PCI bus system. For either reference

Notes:
1. QACK is an output on the MPC8240 and is not required at the COP header for emulation.
2. RUN/STOP normally found on pin 5 of the COP header is not implemented on the MPC8240.
Connect pin 5 of the COP header to OVDD with a 1-k pull-up resistor.
3. CKSTP_OUT normally found on pin 15 of the COP header is not implemented on the MPC8240.
Connect pin 15 of the COP header to OVDD with a 10-k pull-up resistor.
4. Pin 14 is not physically present on the COP header.
