The Counter Tab
The Counter tab allows you view and control the CPLD counter in a visual display. By
using logic design and the internal oscillator as a counter, this design example shows
the time delay before turning on an LED. (CPLDs are frequently used to monitor and
control power IC’s, such as switchers and regulators.)
Figure 5–4 shows the Counter tab.
The following sections describe the controls on the Counter tab.
Counter display —Shows number count and highlights a section around the
circumference.
Seconds —Allows you to enter the number of seconds for the counter from 1 to 10.
