Mode 4: Single-Gated Pulse Generation
This mode generates a single pulse with programmable delay
and programmable pulse-width following software start. The
two programmable 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.

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.
