Functional Description
This section contains a functional description of the major blocks on
the MVME162LX.
Front Panel Switches and Indicators
There are two switches and four LEDs on the front panel of the
MVME162LX.
❏ RESET switch. Resets all onboard devices (including IP
modules, if installed) and drives SYSRESET* if the board is
system controller. The
RESET switch may be disabled by
software.
❏ ABORT switch. When enabled by software, the ABORT switch
generates an interrupt at a user-programmable level. It is
normally used to abort program execution and return to the
162Bug debugger.
❏ FAIL LED (red). Lights when the BRDFAIL* signal line is
active or when the processor is halted. Part of DS1.
❏ RUN LED (green or amber). Lights when the local bus TIP*
signal line is low. This indicates one of the local bus masters
is executing a local bus cycle. Part of DS1.
❏ SCON LED (green). Lights when the VMEchip2 in the
MVME162LX is the VMEbus system controller. Part of DS2.
❏ FUSES LED (green). Lights when +5Vdc, +12Vdc, and -12Vdc
power is available to the LAN and SCSI interfaces and IP
connectors. Part of DS2.
