About This Manual 53
INTP, INTS
The INTP and INTS si
gn
als (PICMG2
.0)
are not supported on the CR! 1.
ENUM#
ENUM
(
PIC
M
G 2.0, open-collector) is available on J700l_C25. This signal is
be driven by Hot Swap compatible boards after insertion and prior to removal.
For CR! I in System Slot, the input ENUM is able to generate au interrupt to
force the software to interrogate all boards within the system for resource
allocation regarding I/0, memory and interrupt usage.
If the CR! I works in a peripheral slot, the non-transparent bridge generate the
o
u
tp
u
t ENUM coufom1 to the specification of a Hot Swap compliant board
.

Geographic Addressing
If the backplane supports geographic Addressing, the CR! I can detect the
wtique Address in a CPCI-System with the GA
