9.3.4 Period Measurement
In period measurement mode, the high-speed input can measure the period of a pulse stream
in one of two modes and provides a continuous indication of the last sampled value. In this
mode, the Disable and Latch special functions are allowed. Refer to the HSC Glossary for a
description of these functions.
Period Rising Edges 1 μs Counts – In this sub-mode the period of the input signal is reported in
one (1) μs units. The period measurement will start on the rising edge of the input.
Period Falling Edges 1 μs Counts – In this sub-mode the period of the input signal is reported in
1 μs units. The period measurement will start on the falling edge of the input.
