PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
System Design Information
Figure 23. COP Connector Diagram
There is no standardized way to number the COP header shown in Figure 23; consequently, many different
pin numbers have been observed from emulator vendors. Some are numbered top-to-bottom then
left-to-right, while others use left-to-right then top-to-bottom, while still others number the pins counter
clockwise from pin one (as with an IC). Regardless of the numbering, the signal placement recommended
in Figure 23 is common to all known emulators.
The QACK signal shown in Table 17 is usually hooked up to the PCI bridge chip in a system and is an input
to the MPC7410 informing it that it can go into the quiescent state. Under normal operation this occurs
during a low power mode selection. In order for COP to work the MPC7410 must see this signal asserted
(pulled down). While shown on the COP header, not all emulator products drive this signal. To preserve
correct power down operation, QACK should be merged so that it also can be driven by the PCI bridge.
Table 17 shows the pin definitions.
