50 Operation Theory
Mode6: Re-triggered Single Pulse Generation
This mode is similar to mode 5 except that the counter gener-
ates a pulse following every active edge on GPTC_GATE.
After the software start, every active GPTC_GATE edge trig-
gers a single pulse with programmable delay and pulse-width.
Any GPTC_GATE trigger that occurs during the pulse genera-
tion is ignored. Figure 4-22 illustrates the generation of two
pulses with pulse delay of two and pulse-width of four.

Mode7: 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. Once the first GPTC_GATE edge triggers the
counter, GPTC_GATE takes no effect until the software start is
re-executed. Figure 4-23 illustrates the generation of two
pulses with pulse delay of four and pulse-width of three.
