Timer Interface Module (TIM)
8.4 Functional Description

that can operate as a free-running counter or a modulo up-counter. The TIM counter provides the timing
reference for the input capture and output compare functions. The TIM counter modulo registers,
TMODH:TMODL, control the modulo value of the TIM counter. Software can read the TIM counter value
at any time without affecting the counting sequence.
The TIM channel (per timer) is programmable independently as input capture or output compare channel.
If a channel is configured as input capture, then an internal pullup device may be enabled for that channel.
