8-bit timer (TIM8)
Introduction
The timer consists of a 8-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 clock prescaler.

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’.
Functional description
Counter
The main block of the Programmable Timer is a 8-bit free running upcounter and its
associated 8-bit registers.
These two read-only 8-bit registers contain the same value but with the difference that
reading the ACTR register does not clear the TOF bit (Timer overflow flag), located in the
Status register, (SR).
Programmable prescaler: f
Overflow status flag and maskable interrupt
