Operation Theory 51
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 4-24 illustrates the generation of two pulses with
pulse delay of four and pulse-width of three.
