Maintenance Panel Operating Connections
3-13. Using Maintenance Panel and System Control Panel
When the Maintenance Panel is in use, switches and indicators
on
the System
Control Panel
(figure
3-1)
function in
the normal
manner.
The following points apply:
a.
The CPU can be started
or
halted
either
by
the
RUN-HALT
switch
on the Maintenance Panel or by the RUN/HALT switch on
the System Control Panel.
b.
If the LOAD
switch on the System Control Panel is used,
the
appropriate
information must be set into the SWITCH REGISTER
on the
System Control Panel.
Similarly,
use
of the
LOAD
sw itch on the Maintenance Panel requires that the SWITCH REG-
ISTER on the
Ma
intenance Panel be used.
c.
The RSW instruction acquires the l6-bit word which is in
the
SWITCH REGISTER
on
the System
Control Panel,
as in normal
operation.
