Hot Swap Detection
The
CompactPCI
specification added the signal ENUM# to the PCI bus to allow the board hot
swapping. This signal is routed to the GPI3 of the ICH9. A System Management Interrupt (SMI) can be
requested if ENUM# changes by insertion or removal of a board.
Note that the CCM-BOOGIE itself is not a hot swap device, because it makes no sense to remove the
system controller from a
CompactPCI
system. However, it is capable to recognize the hot swap of
peripheral boards and to start software that is doing any necessary system reconfiguration.
Power Supply Status (DEG#, FAL#)
Power supply failures may be detected before the system crashes down by monitoring the signals
DEG# or FAL#. These active low lines are additions of the
CompactPCI
specification and may be
driven by the power supply. DEG# signals the degrading of the supply voltages, FAL# there possible
failure. On the CCM-BOOGIE the signal FAL# is routed to the GPI4 and DEG# to the GPI5 of the
ICH9.
PXI Trigger Signals
As an option, the CCM-BOOGIE supports four of the eight trigger signals of the PXI standard, as
defined by National Instruments. The trigger signals are provided by the local SIO (Super-I/O) chip
IT8761E. GPIO20/21 are routed to TRIG0/1, and GPIO26/27 are used to control TRIG6/7. These signals
can also be used as GPIO lines in a non-PXI environment.
