##### How to use this driver #####
==============================================================================
[..] This driver provides functions to configure and program the TIM
of all stm32f30x devices.
These functions are split in 9 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
(#) 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
(#) 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
