Operation Theory 49

Mode4: Single Gated Pulse Generation

This mode generates a single pulse with programmable delay

and programmable pulse-width following the software start.

These software programmable parameters could be specified

in terms of periods of the GPTC_CLK. GPTC_GATE is used to

enable/disable counting. When GPTC_GATE is inactive, the

counter halts the counting. Figure 4-20 illustrates the genera-

tion of a single pulse with pulse-delay of two and pulse-width of

four.

Mode5: Single Triggered Pulse Generation

This function generates a single pulse with programmable

delay and programmable pulse-width following an active

GPTC_GATE edge. These software programmable parame-

ters can be specified 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-executed. Figure 4-21 illustrates the generation of a single

pulse with pulse delay of two and pulse-width of four.
