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 software
start, every active GPTC_GATE edge triggers a single pulse with pro
-
grammable delay and pulse width. Any GPTC_GATE triggers 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.
Figure 3-16: Mode 6-Re-Triggered Single Pulse
Mode 7: Single-Triggered Continuous Pulse Generation
This mode is similar to Mode 5 except that the counter generates
continuous periodic pulses with programmable pulse interval and
pulse-width following the first active edge of GPTC_GATE. When the
first GPTC_GATE edge triggers the counter, GPTC_GATE has no effect
until software start is executed again. Generation of two pulses with
a pulse delay of four and a pulse-width of three is shown.

Mode 8: Continuous Gated Pulse Generation
This mode generates periodic pulses with programmable pulse inter

val and pulse-width following software start. GPTC_GATE
enables/disables calculation. When GPTC_GATE is inactive, the
