The MVME2603/2604 front panel has
ABORT
and
RESET
switches
and six LED (light-emitting diode) status indicators (
CHS
,
BFL
,
CPU
,
PCI
,
FUS
,
SYS
). The switches and LEDs are mounted on an LED
mezzanine board that plugs into the base board.
ABORT Switch (S1)
When activated by software, the
ABORT
switch can generate an
interrupt signal from the base board to the processor at a user-
programmable level. The interrupt is normally used to abort
program execution and return control to the debugger firmware
located in the MVME2603/2604 ROM and Flash memory. The
interrupt signal reaches the processor module via ISA bus interrupt
