Implicit Buffered Pulse-Width Measurement
An implicit buffered pulse-width measurement is similar to single
pulse-width measurement, but buffered pulse-width measurement takes
measurements over multiple pulses.
The counter counts the number of edges on the Source input while the Gate
input remains active. On each trailing edge of the Gate signal, the counter
stores the count in the counter FIFO. A DMA controller transfers the stored
values to host memory.

measurement.
