Board cannot do function
Sets the source of gate control for the specified counter/timer channel. Note
that most boards do not support this function (check your board manual). If
the gate source is set to software then EDR_CTSoftGate can be used to start
and stop the counter.
On the PC30Fxx and PC30Gxx the valid source settings and their effects on
the clock source and ECLK line are shown in the following table. Note that
the num parameter must be 2 for these boards. Also remember that the
EDR_CTClockSource function also sets the direction of the ECLK line.
