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.
Some devices of the ST7 family have two on-chip 16-bit timers. They are completely
independent, and do not share any resources. They are synchronized after a device reset
as long as the timer clock frequencies are not modified.
This description covers one or two 16-bit timers. In the devices with two timers, register
names are prefixed with TA (timer A) or TB (timer B).
Main features
Some timer pins may not be available (not bonded) in some devices. Refer to
Device pin description on page
The block diagram is shown in
When reading an input signal on a non-bonded pin, the value is always ‘1’.
