7.
Call
GPCTR_Control
to start the generation of a square wave. Set the
following parameters:
•
deviceNumber
—The value obtained from MAX
•
gpctrNum
—
0
•
action
—
ND_PROGRAM
8.
The device begins to generate a 5 MHz square wave when the
GPCTR_Control
function completes execution. Compare the value
read by the counter to the test limits in the appropriate table. If the
value falls between these limits, the device has passed the test.
9.
Disconnect the counter from the device.
You have now verified the counter on the device.
