Machine Reset
The Machine Reset switch resets all 2702 registers
and LCW storage, except for the L1 and L2 check
bits.
Completing the reset initiated by this switch takes
1500 usec
±
25%; the 2702 signals Control Unit Busy
if initial selection is attempted during this time.
This switch is effective only when the 2702 is off-
line.
Display Line Ctl Word
This switch determines what information is captured
and displayed by the capture register; this information
is retrieved from the LCW of the communications
line selected by the Test-LCW Address switches.
With the Display Line Ctl Word switch in the A
position, the first 16 bits of the addressed LCW from
each delay line (L1 and L2) are captured and dis-
played.
With the Display Line Ctl Word switch in the B
position, the last 16 bits of the addressed LCW from
each delay line (L1 and L2) are captured and dis-
played.
With the Display Line Ctl Word switch in the S,
IO-LA position, the I/O register contents, the line-
adapter interface with the common controls, and the
S-line segment (if feature is used) are captured and
displayed.
Line Zero/Test- LCW Adr Switch
The Line Zero/Test-LCW Adr switch determines the
capture register display.
When this switch is in the LINE ZERO position,
the capture register will display, for line zero, the
fields selected by the Display Line Ctl Word switch.
When this switch is in the TEST-LCW ADR posi-
tion, the capture register will display the same infor-
mation for the line address entered in the Test-LCW
Address switches.
Test- LCW Address 1, 2, 4, 8, and 16
These switches are used to select a 2702 line to be
wrapped, displayed, or modified.
