Geographic Addressing
If the backplane supports geographic addressing, the VR11 can detect the
unique address in a VME System with the GA [4...0] pins on the P73001.
For programming information please see the 'Board Specific Hardware
Programmer’s Manual'.
GPIO (0...7)
Eight GPIO-Pins are available on the P7302. These pins can be used for I/O
functions with output 3.3 V signals as well as 5 V tolerant inputs. They can be
used only when the TMDS is not installed. GPIO and TMDS are mutually
exclusive ordering options. For more information please see the ‘Board
Specific Hardware Programmer’s Manual.
Watchdog, Powerfail Monitor
In order to secure application software, the VR11 offers a software controlled
hardware two stage counter 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 1us to
10 min.
For more information please see the Intel 6300ESB I/O Controller Hub
datasheet and the ‘Board Specific Hardware Programmer’s Manual’.
Programmable Timer
An additional programmable Timer is implemented on the VR11. The timer
can generate an Interrupt. For more information please see the ''Board Specific
Hardware Programmer’s Manual'.
LED
The Status LED is a amber/green/red tri-color for BIOS power-up status
indication. After boot-loading, the user software is free to use this LED for its
own purpose.
