Operation Theory 53
Mode 5: Single Triggered Pulse Generation
This mode generates a single pulse with programmable delay
and programmable pulse-width following an active
GPTC_GATE edge. You may specify these programmable
parameters in terms of periods of the GPTC_CLK input. When
the first GPTC_GATE edge triggers the single pulse,
GPTC_GATE makes no effect until the software-start is
executed again. Figure 4-22 illustrates the generation of a single
pulse with a pulse delay of two and a pulse-width of four.
Figure 4-22: Mode 5 Operation
Mode 6: Re-triggered Single Pulse Generation
This mode is similar to Mode 5 except that the counter
generates a pulse following every active edge of GPTC_GATE.
After the software-start, every active GPTC_GATE edge
triggers a single pulse with programmable delay and pulse-
width. Any GPTC_GATE triggers that occur when the prior
pulse is not completed is ignored. Figure 4-23 illustrates the
generation of two pulses with a pulse delay of two and a pulse-width
of four.
