8.4.3.7 GO PIN FUNCTIONALITY
This option allows the user to change the functionality of the go pin. When you select
this menu option, a message appears with the current setting and offers four options
(see Figure 8-5).
FIGURE 8-5: GO PIN FUNCTIONALITY SCREEN
The default setting is “Use as PgmVfy” (“Currently: as Program Verify”). The setting is
saved when the programmer is powered off.
This feature is especially useful on the production line where speed in processing a
device is required. It enables repeated operations to be performed on devices as they
are automatically loaded/unloaded into the programmer. Each time the device is
loaded, the Go pin is activated and the preset operation is performed.
The “Currently:” display changes to reflect the selected option.
