Timer Interface Module (TIM1)
17.1 Introduction
This section describes the timer interface module (TIM1). TIM1 is a two-channel timer that provides a
timing reference with input capture, output compare, and pulse-width-modulation functions.
is a block diagram of the TIM1.
17.2 Features
Features of the TIM1 include the following:

counter that can operate as a free-running counter or a modulo up-counter. The TIM1 counter provides
the timing reference for the input capture and output compare functions. The TIM1 counter modulo
registers, T1MODH:T1MODL, control the modulo value of the TIM1 counter. Software can read the TIM1
counter value at any time without affecting the counting sequence.
The two TIM1 channels are programmable independently as input capture or output compare channels.
