Timer Interface Module (TIM1)
16.1 Introduction
This section describes the timer interface module (TIM1). The TIM1 module is a 4-channel timer that
provides a timing reference with input capture, output compare, and pulse-width-modulation functions.
The TIM1 module shares its pins with general-purpose input/output (I/O) port pins. See
port location of these shared pins.
16.2 Features
Features include the following:
16.3 Functional Description

can operate as a free-running counter or a modulo up-counter. The 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 counter. Software can read the counter value,
T1CNTH:T1CNTL, at any time without affecting the counting sequence.
The four TIM1 channels are programmable independently as input capture or output compare channels.
