/** @page TIM4_TimeBase_InterruptConfiguration Toggling an output with TIM4 update interrupt
@par Example description
This example provides a short description of how to use the TIM4 peripheral
In this example, the PG.5 pin toggles each time the Update interrupt occurs
The TIM4CLK frequency is 2MHz, the Prescaler is 1 so the TIM4 counter clock is 2MHz.
The TIM4 is running at 7.8125 KHz: TIM4 Frequency = TIM4 counter clock/(ARR value + 1)
So the TIM4 generates an Update Interrupt each 128 us.
@note The square signal frequency on PG.5 is the half of Update Interrupt frequency
(signal Period = 2 x Update interrupt period).

@par Hardware and Software environment
- This example was developped to run on STM8S208 device with STMicroelectronics
STM8/128-EVAL evaluation board.
- It can be tailored to run on any other supported device and developpement board.
- This example has been tested with ST Visual Develop (STVD) toolchain
(Cosmic and Raisonance compilers).
- STM8/128-EVAL Set-up
- Connect PG.5 pin to an oscilloscope.
@par How to use it ?
In order to make the program work, you must do the following :
- Create a project and setup all project configuration
- Add the required Library files :
- stm8s_tim4.c
- stm8s_gpio.c
- Edit stm8s.h file to select the device you are working on (#define STM8S208, in this case).
@b Tip: You can tailor the provided project template to run this example, for more
details please refer to "stm8s_fwlib_um.chm" user manual; select "Peripheral Examples"
then follow the instructions provided in "How to proceed" section.
