Some of these options may not be available in some driver software.
Counter n TC is an internal signal that asserts when the counter value is 0.
The Counter n Internal Output signal changes in response to Counter n TC.
The two software-selectable output options are pulse on TC and toggle
output polarity on TC. The output polarity is software-selectable for both
options.
Routing Counter n Internal Output to an Output
Terminal
You can route Counter n Internal Output to any PFI <4..7> or PFI <12..15>
terminal.
The Frequency Output (FREQ OUT) signal is the output of the frequency
output generator.

Routing Frequency Output to a Terminal

You can route Frequency Output to any PFI <4..7> or PFI <12..15>
terminal.
By default, NI-DAQmx routes the counter/timer inputs and outputs to the
PFI pins, shown in Tables 9-5 and 9-6.
