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 two TIM channels are programmable independently as input capture or output compare channels. If
a channel is configured as input capture, then an internal pullup device may be enabled for that channel. .
