HARDWARE CONFIGURATION
2– 30
2.2.3 Pulse-width Count Timer (Timer 2)
This timer has timer and pulse-width measurement functions.
The timer function has two modes: reload timer and one-shot.
In the reload timer mode, the set values are counted down repeatedly.
In the one-shot mode, counting down is started from the set values and
stops at the first underflow.
The pulse-width measurement function enables measurement of High,
Low, or one-cycle widths of pulses input from pins.
For inputting from pins, the 5-bit noise-clearing circuit is selectable.
