The editor screen allows you to view the fusemap of the logic device under test, and
also allows you to edit the fusemap manually if necessary. As can be seen in the
figure above, a portion of the addressable fuse locations is displayed. If there is a “–”
symbol in any location, that fuse has been blown, while the “X” symbol indicates that
the fuse is still intact. Some of the additional controls on the screen include:
x All to ‘–’—Blows all fuses in the device
x All to ‘X’—Connects all fuses in the device
x Set Line to ‘–’—Blows all fuses in the line that has been selected by the mouse

x Set Line to ‘X’—Connects all fuses in the line that has been selected by the
mouse cursor; indicated by the highlighted line
x Home—Sends the cursor back to the beginning fuse location of the device
x End—Sends the cursor to the last fuse location of the device
