ABORT Switch (S1)
The ABORT switch sends an interrupt signal to the processor. The interrupt
is normally used to abort program execution and return control to the
debugger firmware located in the MVME2700 EPROM and Flash
memory.
The interrupter connected to the ABORT switch is an edge-sensitive circuit,
filtered to remove switch bounce.
RESET Switch (S2)
The RESET switch resets all onboard devices; it also drives a SYSRESET?
signal if the MVME2700 is the system controller. SYSRESET? signals may
be generated by the RESET switch, a power-up reset, a watchdog timeout,
or by a control bit in the Miscellaneous Control Register (MISC_CTL) in
the Universe II ASIC. For further details,nel Indicators (DS1 – DS6)
There are six LEDs on the MVME2700 front panel. The LEDs perform the
functions listed below.Notes
1. At reset, a lamp test function illuminates all the LEDs.
2. Because the FUS LED monitors the status of several voltages on the
MVME2700, it does not directly indicate the condition of any single
fuse. If the LED flickers or goes out, check all the fuses
(polyswitches) described in Chapter 3, Functional Description.Memory Maps
There are three points of view for memory maps:
? The mapping of all resources as viewed by the processor (MPU bus
memory map)
? The mapping of onboard resources as viewed by PCI local bus
masters (PCI bus memory map)
? The mapping of onboard resources as viewed by VMEbus masters
(VMEbus memory map)
The following sections give a general description of the MVME2700
memory organization from the above three points of view. Detailed
memory maps can be found in the MVME2600/2700 Series Single Board
Computer Programmer’s Reference Guide, which is also applicable to the
MVME2700.
Processor Memory Map
The processor memory map configuration is under the control of the
Raven bridge controller ASIC and the Falcon memory controller chip set.
The Raven and Falcon devices adjust system mapping to suit a given
application via programmable map decoder registers. At system power-up
or reset, a default processor memory map takes over.
