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.

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 soft-
ware start, every active GPTC_GATE edge triggers a single pulse
with programmable delay and pulse width. Any GPTC_GATE trig-
gers that occur when the prior pulse is not completed are ignored.
Generation of two pulses with a pulse delay of two and a pulse
width of four is shown.
