54 Operation Theory
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 makes no effect until the software-start
is executed again. Figure 4-24 illustrates the generation of two pulses
with a pulse delay of four and a pulse-width of three.

Mode 8: Continuous Gated Pulse Generation
This mode generates periodic pulses with programmable pulse
interval and pulse-width following the software-start.
GPTC_GATE is use to enable/disable counting. When
GPTC_GATE is inactive, the counter halts the current count
value. Figure 4-25 illustrates the generation of two pulses with a
pulse delay of four and a pulse-width of three.
