What Up-Down counter are you referring to?

Time base counter register (up down mode).

It is used to compare with modulating waveform.

This is from the EPWM module then? you want to see the direction (1, or 0) on the GPIO?

Yes

Or is this can see through DAC like 0 to TBPRD and TBPRD to 0 in DSO.

To see it on a GPIO, THROUGH HW and not a SW solution, you can use TBCTR dir as an input to the CLB, then pass that to the CLB1-4 OUT4 or OUT5. Then use OUTPUT XBAR to put it on a pin.

The TBCTR value showing on the DAC output, that will have to a SW solution where you manually copy, the TBCTR value in to the DACVAL register. (Not recommended).
