Width High 1 µs Counts – In this sub-mode the accumulator value will contain the number of 1 µs counts
the pulse is high.
Width Low 1 µs Counts - In this sub-mode the accumulator value will contain the number of 1 µs counts
the pulse is low.

11.3.4 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 11.2 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 one (1)
µs units. The period measurement will start on the falling edge of the input.
