Jumpers - HP 10314D User Manual

Jumpers
The
State/Timing
Switch
The jumpers on the preprocessor interface board allow you to select
different signals for analysis. These jumpers are set at the factory to
view the READY, ADS, BUSY, and PEREQ signals on status bits 12
through 15. Figure 1-1 shows the location of the jumpers.
• J8 (pod
5,
bit 15) allows you to select between READY and
NMI.
• J7 (pod
5,
bit 14) allows you to select between ADS and INTR.
• J6 (pod
5,
bit 13) allows you to select between BUSY and
READY.
• JS (pod
5,
bit 12) allows you to select between PER and ADS.
If you move the jumpers, you must update the Format menu to reflect
your changes. To update the Format menu:
1. If you move the jumper on J8 to the NMI position, change the
READY label to read NMI.
2. If you move the jumper on J7 to the INTR position, modify the
ADS label to read INTR.
3.
If you move the jumper on J6 to the READY position, assign pod
5
of the READY label to bit 13 instead of bit 15.
4.
If you move the jumper on JS to the ADS position, assign pod 5
of the ADS label to bit 12 instead of bit 14.
5.
Turn off any unused labels.
Figure 2-2 (page 2-2) shows the Format menu when the jumpers are set
to select the NMI, INTR, READY, and ADS signals.
The Statetriming switch allows you to configure the HP 10314D
preprocessor interface for either state or timing analysis. For state
analysis, this
switch must be set to the far-right position as shown on
the preprocessor interface board (see figure 1-1).
For
timing
analysis,
this
switch
is
set to the far-left position.
In this
position the signals are buffered straight through the preprocessor
interface, adding only minimal skew to signals.
