10.5 Using analyzer input signals

The ST7 EMU3 emulator allows you to use eight external input signals (TTL level). These

input signals can be used as other events (see Section 10.2.3 on page 300) in the

programming of Advanced Breakpoints.

You can view the value of the Analyzer probe input at any time, using STVD. From the main

menu, select View>Trace. The input signal value is listed in the Analyzer Probe column.

STVD’s Advanced Breakpoints allows you to use these input signals to define an event.

From the main menu, select Debug Instrument > Advanced Breakpoints to open the

dialog box.
