##### How to use this driver #####
===============================================================================
[..] This driver provides functions to configure and program the TIM
of all STM32L1xx devices These functions are split in 8 groups:
(#) TIM TimeBase management: this group includes all needed functions
to configure the TM Timebase unit:
(++) Set/Get Prescaler.
(++) Set/Get Autoreload.
(++) Counter modes configuration.
(++) Set Clock division.
(++) Select the One Pulse mode.
(++) Update Request Configuration.
(++) Update Disable Configuration.
(++) Auto-Preload Configuration.
(++) Enable/Disable the counter.
(#) TIM Output Compare management: this group includes all needed
functions to configure the Capture/Compare unit used in Output
compare mode:
(++) Configure each channel, independently, in Output Compare mode.
(++) Select the output compare modes.
(++) Select the Polarities of each channel.
(++) Set/Get the Capture/Compare register values.
(++) Select the Output Compare Fast mode.
(++) Select the Output Compare Forced mode.
(++) Output Compare-Preload Configuration.
(++) Clear Output Compare Reference.
(++) Select the OCREF Clear signal.
(++) Enable/Disable the Capture/Compare Channels.
(#) TIM Input Capture management: this group includes all needed
functions to configure the Capture/Compare unit used in
Input Capture mode:
(++) Configure each channel in input capture mode.
(++) Configure Channel1/2 in PWM Input mode.
(++) Set the Input Capture Prescaler.
(++) Get the Capture/Compare values.
(#) TIM interrupts, DMA and flags management.
(++) Enable/Disable interrupt sources.
(++) Get flags status.
(++) Clear flags/ Pending bits.
(++) Enable/Disable DMA requests.
(++) Configure DMA burst mode.
(++) Select CaptureCompare DMA request.
(#) TIM clocks management: this group includes all needed functions
to configure the clock controller unit:
(++) Select internal/External clock.
(++) Select the external clock mode: ETR(Mode1/Mode2), TIx or ITRx.
(#) TIM synchronization management: this group includes all needed.
functions to configure the Synchronization unit:
(++) Select Input Trigger.
(++) Select Output Trigger.
(++) Select Master Slave Mode.
(++) ETR Configuration when used as external trigger.
(#) TIM specific interface management, this group includes all
needed functions to use the specific TIM interface:
(++) Encoder Interface Configuration.
(++) Select Hall Sensor.
(#) TIM specific remapping management includes the Remapping
configuration of specific timers

##### TimeBase management functions #####
===============================================================================
*** TIM Driver: how to use it in Timing(Time base) Mode ***
===============================================================================
[..] To use the Timer in Timing(Time base) mode, the following steps are
mandatory:
(#) Enable TIM clock using
RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function.
(#) Fill the TIM_TimeBaseInitStruct with the desired parameters.
(#) Call TIM_TimeBaseInit(TIMx, &TIM_TimeBaseInitStruct) to configure
the Time Base unit with the corresponding configuration.
(#) Enable the NVIC if you need to generate the update interrupt.
(#) Enable the corresponding interrupt using the function
TIM_ITConfig(TIMx, TIM_IT_Update).
(#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
[..]
(@) All other functions can be used seperatly to modify, if needed,
