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. Please see section 12.2 for a
description of these functions.
Period Rising Edges 1μs 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 1μs 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 falling edge of the input.
