Figure 3-17: Mode 7-Single-Triggered Continuous Pulse
Mode 8: Continuous Gated Pulse Generation
This mode generates periodic pulses with programmable pulse
interval and pulse-width following software start. GPTC_GATE
enables/disables calculation. When GPTC_GATE is inactive,
the counter halts the current count value. Generation of two
pulses with a pulse delay of four and a pulse-width of three is
shown.
Figure 3-18: Mode 8-Continuous Gated Pulse
Mode 9: Edge Separation Measurement
Measures the time differentiation between two different pulse
signals. The first pulse signal is connected to GPTC_GATE
and the second signal is connected to GPTC_AUX. Clocks that
pass between the rising edge signal of two different pulses
through the 40 MHz internal clock or external clock are calcu-
lated. You can calculate the time period via the known clock
frequency. The maximum counting width is 32-bit. Decrease of
