Operation Theory 55
GPTC_GATE is used to enable/disable counting. When
GPTC_GATE is inactive, the counter halts the current count
value. Figure 4-26 illustrates the generation of a single pulse
with a pulse delay of two and a pulse-width of four.
Figure 4-26: Mode 4 Operation
Mode 5: Single Triggered Pulse Generation
This function generates a single pulse with programmable
delay and pro-grammable pulse-width following an active
GPTC_GATE edge. You could specify these programmable
parameters in terms of periods of the GPTC_CLK input. Once
the first GPTC_GATE edge triggers the single pulse,
GPTC_GATE takes no effect until the software-start is re-exe-
cuted. Figure 4-27 illustrates the generation of a single pulse
with a pulse delay of two and a pulse-width of four.
