Timer Interface Module (TIM2)
18.1 Introduction
This section describes the timer interface module (TIM2). The TIM2 is a 6-channel timer that provides a
timing reference with input capture, output compare, and pulse-width-modulation functions.

can operate as a free-running counter or a modulo up-counter. The TIM2 counter provides the timing
reference for the input capture and output compare functions. The TIM2 counter modulo registers,
T2MODH:T2MODL, control the modulo value of the TIM2 counter. Software can read the TIM2 counter
value at any time without affecting the counting sequence.
The six TIM2 channels are programmable independently as input capture or output compare channels.
