Make sure that the signals are wired appropriately. Refer to
for an example of
connecting a frequency measurement application.
Rate Generation
Use rate generation mode to generate a continuous pulse output signal from Counter 0 Out;
this mode is sometimes referred to as continuous pulse output or pulse train output.
The pulse output operation is enabled whenever the Counter 0 Gate signal is active (high level
or software gate). While the pulse output operation is enabled, the counter outputs a
high-to-low going pulse with a pulse width of 50% continuously. As soon as the operation is
disabled, rate generation stops.
The frequency of the output signal is determined by the C/T clock source (either internal or
external) and, for an external clock source, the clock divider used. You can generate an output
signal from Counter 0 Out with a frequency of 60 Hz to 6 MHz.
To specify rate generation mode, use software to specify the counter/timer mode as rate, the
C/T clock source as either internal or external, the clock divider (2 to 65534) if an external
clock source is used, and the active gate type (low-level, high-level, or software gate). Refer to
for more information about gate types.
Make sure that the signals are wired appropriately. Refer to
for an example of
connecting a rate generation application.
