Mode 4: Single Gated Pulse Generation
This generates a single pulse with programmable delay and
programmable pulse-width following the software-start. The
two programmable parameters can be specified in terms of
periods of the GPTC_CLK input by the software application.
GPTC_GATE is use to enable/disable counting. When
GPTC_GATE is inactive, the counter halts the current count
value. Figure 4-21 illustrates the generation of a single pulse
with a pulse delay of two and a pulse-width of four.
