3.3.1 Reset/Abort Switch
The MVME4100ET has a single push button switch to provide both the abort and reset
functions. When the switch is depressed for less than 3 seconds, an abort interrupt is
generated to the MPC8548E PIC. If the switch is held for more than 3 seconds, a board hard
reset is generated. If the MVME4100ET is the VMEbus system controller, a VME SYSRESET is
generated.
3.3.2 LEDs
The table below describes the LEDs on the front panel of the MVME4100ET. Refer to Figure 3-2
on page 47 for LED locations.
