Mode7: Single Triggered Continuous Pulse Generation
This mode is similar to Mode5 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 4-29 illustrates the generation of two
pulses with a pulse delay of four and a pulse-width of three.

Mode8: Continuous Gated Pulse Generation
This mode generates periodic pulses with programmable pulse
interval and pulse-width following the software-start.
GPTC_GATE is used to enable/disable counting. When
GPTC_GATE is inactive, the counter halts the current count
value. Figure 4-30 illustrates the generation of two pulses with
a pulse delay of four and a pulse-width of three.
