Note:
(1)
These signals are not connected.
(2)
These signals are pulled high onboard.
(3)
These signals are pulled low onboard.
(4)
These power pins are used for cPCI-R6760S and
cPCI-R6760D. If the backplane has any power pins
connected to those pins, it will not allow operators
to remove or insert the cPCI-6760D front board in a
live system.
(5)
ENUM# is connected to a BIOS programmable
circuitry then connected to either IRQ 3 or IRQ 9
depending on hardware configuration. There is a
BIOS setting to Enable/Disable this ENUM#
function. The default BIOS setting is set to disabled
and the factory default hardware configuration is
IRQ 9. To support PICMG 2.1 hot-swap for
peripheral boards, the backplane should bus all
peripheral slots ENUM# together to system slot.
Customers should also enable the ENUM# function
in the cPCI-6760D BIOS setting. (When R283 and
R284 are installed with 0-ohm resistors, ENUM# is
routed through IRQ9. If R283 and R284 are
removed and R281 and R282 are installed with 0-
ohm resistors, ENUM# is routed through IRQ3.)
(6)
M66EN is tied to the ground. PCI bus can run in
33MHz.
(7)
In backplanes, BDSEL must tie to ground to enable
the “self-hot-swap” controller.
(8)
IDSEL is tied to ground.
