Issue Details:
This document outlines how to use pulse width measurement, one of the several GPTC functions
available to users.
●
More information:
Single period measurement calculates the period of the signal from GPTC_GATE in terms of
GPTC_CLK signal. The counter calculates the number of active edges on GPTC_CLK between two
active edges of GPTC_GATE.
Single pulse width measurement calculates the pulse width of the signal from GPTC_GATE in terms
of GPTC_CLK. The counter calculates the number of active edges on GPTC_CLK.
