16-bit timer
Introduction
The timer consists of a 16-bit free-running counter driven by a programmable prescaler.
It may be used for a variety of purposes, including pulse length measurement of up to two
input signals (input capture) or generation of up to two output waveforms (output compare
and PWM).
Pulse lengths and waveform periods can be modulated from a few microseconds to several
milliseconds using the timer prescaler and the CPU clock prescaler.

When reading an input signal on a non-bonded pin, the value is always ‘1’.
Functional description
Counter
The main block of the programmable timer is a 16-bit free running upcounter and its
associated 16-bit registers. The 16-bit registers are made up of two 8-bit registers called
high and low.
