The COP interface has a standard header for connection to the target system, based on the
0.025” square-post 0.100” centered header assembly (often called a “Berg” header). The con-
nector typically has pin 14 removed as a connector key.

There is no standardized way to number the COP header shown in
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
The QACK signal shown in
a system and is an input to the PC755 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
PC755 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.
