Mode 4: Single-Gated Pulse Generation
This mode generates a single pulse with programmable delay and
programmable pulse-width following software start. The two pro-
grammable parameters can be specified in terms of periods of the
GPTC_CLK input by the software application. GPTC_GATE
enables/disables calculation. When GPTC_GATE is inactive, the
counter halts the current count value. Generation of a single pulse
with a pulse delay of two and a pulse-width of four is shown.
Figure 3-17: Mode 4-Single-Gated Pulse
Mode 5: Single-Triggered Pulse
This mode generates a single pulse with programmable delay and
programmable pulse-width following an active GPTC_GATE edge.
These programmable parameters can be specified in terms of
periods of the GPTC_CLK input. When the first GPTC_GATE
edge triggers the single pulse, GPTC_GATE has no effect until
software start is executed again. Generation of a single pulse with
a pulse delay of two and a pulse-width of four is shown.
