7.13.8 PWM High Time (Object 0x3178, 0x317A, 0x317C, 0x317E)
Objects 0x3178, 0x317A, 0x317C, 0x317E are 16-bit count registers used to
record the high time for the signal present at the corresponding inputs.
This high time is the time that passes between the rising and falling edges of
the signal at the digital input. When a rising signal edge is detected, a coun-
ter will start being incremented every
μ s. Then, when the corresponding fall-
ing signal edge is detected, the counter value will be recorded in the corre-
sponding 16-bit PwmHighTime(x) count register. Once the value is
transferred to PwmHighTime(x), the counter will be reset.
