6.6.9.3 Free-up a DCO or VCO's Timer/Counters - TCfreeDCO
Frees the timer/counter & DIO resources used by a DCO, or VCO, as previously setup by
TCsetDCO or TCsetVCO. Call this function when you’ve finished using the DCO or VCO.
i = TCfreeDCO (h, hO)
where
h Integer. Board handle as issued by function
registerBoard.
hO Integer. DCO or VCO handle, as issued by
TCsetDCO or TCsetVCO, respectively.
