This function resets both channels of the PG2 to the default settings of the specified
pulse mode. The default setting for each parameter is listed in the Format section for
each LPT function.
The pulse_init function can be used to reset the pulse generator card to the default
settings for the presently selected pulse mode.
This function resets the PG2 to the Segment ARB pulse mode and its default settings:
pg2_init(VPU1, 1)
Sets count for pulse burst mode
For the burst mode, this function sets the number of pulses to output during a burst
sequence.
