Introduction
This chapter provides information on powering up the MVME162P2 VME
Embedded Controller after its installation in a system, and describes the
functionality of the switches, status indicators, and I/O ports.
For programming information, consult the MVME1X2P2 VME Embedded
Controller Programmer’s Reference Guide.
Front Panel Switches and Indicators
There are two switches
(ABORT
and
RESET
) and four LEDs (
FAIL, RUN,
FUSES, SCON
) located on the MVME162P2 front panel.

Control/Indicator Function
Abort Switch ( ABORT ) 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 MVME162P2 Flash memory.
The interrupter connected to the Abort switch is an edge-sensitive
circuit, filtered to remove switch bounce.
Reset Switch ( RESET ) Resets all onboard devices. Also drives a SYSRESET
∗
signal if the
MVME162P2 is 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 Local Control/Status Register
(LCSR) in the VMEchip2 ASIC. For further details, refer to
Chapter 4, Functional Description.
