Figure 3-15: Mode 5-Single-Triggered Pulse
Mode 6: Re-Triggered Single Pulse Generation
This mode is similar to Mode 5 except that the counter gener-
ates a pulse following every active edge of GPTC_GATE. After
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 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 gener-
ates continuous periodic pulses with programmable pulse inter-
val 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 exe-
cuted again. Generation of two pulses with a pulse delay of
four and a pulse-width of three is shown.
