62 CP9*, CR9*, CT9* Celeron M/Pentium M
Publication No. HRMCP9 Rev. B
For CR9 in System Slot, the input ENUM is able to generate an interrupt to force the
software to interrogate all boards within the system for resource allocation regarding
I/O, memory and interrupt usage.
If the CR9 works in a peripheral slot, the non-transparent bridge generates the
output ENUM conform to the specification of a Hot Swap compliant board. For
programming information about this PnP device, please see the 'AMI-BIOS for CR9,
CP9, CT9 User’s and Programmer’s Manual'.
7.17.10
Geographic Addressing
If the backplane supports geographic Addressing, the CR9 can detect the unique
Address in a CPCI-System with the GA [4...0] pins (PICMG 2.0) on J7002.
For programming information please see the 'AMI-BIOS for CR9, CP9, CT9 User’s
and Programmer’s Manual'. For more information about geographic addressing in
appliance to system management, see PICMG 2.9.
7.17.11
GPIO (0..7)
Eight GPIO pins are available on J7004. These pins can be used for I/O functions with
output 3.3 V signals as well as 5 V tolerant inputs.
For more information please see the ‘Board Specific Hardware Programmer’s
Manual’.
7.17.12
Watchdog
For security of application software, the CR9 offers a software controlled hardware
two stage watchdog with independent count values for each stage. First stage
generates an INT or SMI. The second stage issuing a reset signal if its time-out
interval expires. The configurable granularity reaches from 1µs to 10min.
For more information please see the Intel ICH4 I/O Controller Hub datasheet and the
‘Board Specific Hardware Programmer’s Manual’.
7.17.13
Programmable Timer
An additional programmable Timer is implemented on the CR9. The timer can
generate an Interrupt.
For more information please see the ‘Board Specific Hardware Programmer’s
Manual’.
7.17.14
LEDs
Two LEDs are available at the front panel green/red and blue.
The Status LED is a green/red bi-color for BIOS power-up status indication, after
boot loading the user software is free to use this LED for its own purpose.
