15.3. General level1 timer (TIMERx, x=8, 11)
15.3.1.
Overview
The general level1 timer module (Timer8, 11) is a two-channel timer that supports input
capture, output compare. They can generate PWM signals to control motor or be used for
power management applications. The general level1 time reference is a 16-bit counter that
can be used as an unsigned counter.
In addition, the general level1 timers can be programmed and be used to count or time
external events that drive other timers.
Timer and timer are completely independent, but there may be synchronized to provide a
larger timer with their counters incrementing in unison.
The general level1 timer module (Timer8, 11) is available only in the GD32F10x_XD devices.
