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 ST7 devices have two on-chip 16-bit timers. They are completely independent, and
do not share any resources. They are synchronized after a MCU reset as long as the timer
clock frequencies are not modified.
This description covers one or two 16-bit timers. In ST7 devices with two timers, register
names are prefixed with TA (Timer A) or TB (Timer B).

a. Some timer pins may not be available (not bonded) in some ST7 devices. Refer to the device pin out
description.
When reading an input signal on a non-bonded pin, the value will always be ‘1’.
