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.

Mode 9: Edge Separation Measurement
Measures the time differentiation between two different pulse sig-
nals. 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
80 MHz internal clock or external clock are calculated. You can
calculate the time period via the known clock frequency. The max-
