* @date 30-September-2011
* @brief This file provides firmware functions to manage the following
* functionalities of the TIM peripheral:
* - TimeBase management
* - Output Compare management
* - Input Capture management
* - Advanced-control timers (TIM1 and TIM8) specific features
* - Interrupts, DMA and flags management
* - Clocks management
* - Synchronization management
* - Specific interface management

* ===================================================================
* How to use this driver
* ===================================================================
* This driver provides functions to configure and program the TIM
* of all STM32F4xx devices.
* These functions are split in 9 groups:
*
* 1. 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
*
* 2. 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
*
* 3. 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
*
* 4. Advanced-control timers (TIM1 and TIM8) specific features
* - Configures the Break input, dead time, Lock level, the OSSI,
* the OSSR State and the AOE(automatic output enable)
* - Enable/Disable the TIM peripheral Main Outputs
* - Select the Commutation event
* - Set/Reset the Capture Compare Preload Control bit
*
* 5. 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
*
* 6. 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
*
* 7. 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
*
* 8. TIM specific interface management, this group includes all
* needed functions to use the specific TIM interface:
* - Encoder Interface Configuration
* - Select Hall Sensor
*
* 9. TIM specific remapping management includes the Remapping
* configuration of specific timers
