* @brief MDIOS HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the MDIOS Peripheral.
* + Initialization and de-initialization functions
* + IO operation functions
* + Peripheral Control functions
*
*
@verbatim
===============================================================================
##### How to use this driver #####
===============================================================================
[..]
The MDIOS HAL driver can be used as follow:
(#) Declare a MDIOS_HandleTypeDef handle structure.
(#) Initialize the MDIOS low level resources by implementing the HAL_MDIOS_MspInit() API:
(##) Enable the MDIOS interface clock.
(##) MDIOS pins configuration:
(+++) Enable clocks for the MDIOS GPIOs.
(+++) Configure the MDIOS pins as alternate function.
(##) NVIC configuration if you need to use interrupt process:
(+++) Configure the MDIOS interrupt priority.
(+++) Enable the NVIC MDIOS IRQ handle.
(#) Program the Port Address and the Preamble Check in the Init structure.
(#) Initialize the MDIOS registers by calling the HAL_MDIOS_Init() API.
(#) Perform direct slave read/write operations using the following APIs:
(##) Read the value of a DINn register: HAL_MDIOS_ReadReg()
(##) Write a value to a DOUTn register: HAL_MDIOS_WriteReg()
(#) Get the Master read/write operations flags using the following APIs:
(##) Bit map of DOUTn registers read by Master: HAL_MDIOS_GetReadRegAddress()
(##) Bit map of DINn registers written by Master : HAL_MDIOS_GetWrittenRegAddress()
(#) Clear the read/write flags using the following APIs:
(##) Clear read flags of a set of registers: HAL_MDIOS_ClearReadRegAddress()
(##) Clear write flags of a set of registers: HAL_MDIOS_ClearWriteRegAddress()
(#) Enable interrupts on events using HAL_MDIOS_EnableEvents(), when called
the MDIOS will generate an interrupt in the following cases:
(##) a DINn register written by the Master
(##) a DOUTn register read by the Master
(##) an error occur
(@) A callback is executed for each genereted interrupt, so the driver provide the following
HAL_MDIOS_WriteCpltCallback(), HAL_MDIOS_ReadCpltCallback() and HAL_MDIOS_ErrorCallback()
(@) HAL_MDIOS_IRQHandler() must be called from the MDIOS IRQ Handler, to handle the interrupt
and execute the previous callbacks
(#) Reset the MDIOS peripheral and all related ressources by calling the HAL_MDIOS_DeInit() API.
(##) HAL_MDIOS_MspDeInit() must be implemented to reset low level ressources
(GPIO, Clocks, NVIC configuration ...)
*** Callback registration ***
=============================================
The compilation define USE_HAL_MDIOS_REGISTER_CALLBACKS when set to 1
allows the user to configure dynamically the driver callbacks.
Use Function @ref HAL_MDIOS_RegisterCallback() to register an interrupt callback.
Function @ref HAL_MDIOS_RegisterCallback() allows to register following callbacks:
(+) WriteCpltCallback : Write Complete Callback.
(+) ReadCpltCallback : Read Complete Callback.
(+) ErrorCallback : Error Callback.
(+) WakeUpCallback : Wake UP Callback
(+) MspInitCallback : MspInit Callback.
(+) MspDeInitCallback : MspDeInit Callback.
This function takes as parameters the HAL peripheral handle, the Callback ID
and a pointer to the user callback function.
Use function @ref HAL_MDIOS_UnRegisterCallback() to reset a callback to the default
weak function.
@ref HAL_MDIOS_UnRegisterCallback takes as parameters the HAL peripheral handle,
and the Callback ID.
This function allows to reset following callbacks:
(+) WriteCpltCallback : Write Complete Callback.
(+) ReadCpltCallback : Read Complete Callback.
(+) ErrorCallback : Error Callback.
(+) WakeUpCallback : Wake UP Callback
(+) MspInitCallback : MspInit Callback.
(+) MspDeInitCallback : MspDeInit Callback.
By default, after the HAL_MDIOS_Init and when the state is HAL_MDIOS_STATE_RESET
all callbacks are set to the corresponding weak functions:
examples @ref HAL_MDIOS_WriteCpltCallback(), @ref HAL_MDIOS_ReadCpltCallback().
Exception done for MspInit and MspDeInit functions that are
reset to the legacy weak function in the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit only when
these callbacks are null (not registered beforehand).
if not, MspInit or MspDeInit are not null, the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit
keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
Callbacks can be registered/unregistered in HAL_MDIOS_STATE_READY state only.
Exception done MspInit/MspDeInit that can be registered/unregistered
in HAL_MDIOS_STATE_READY or HAL_MDIOS_STATE_RESET state,
thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
In that case first register the MspInit/MspDeInit user callbacks
using @ref HAL_MDIOS_RegisterCallback() before calling @ref HAL_MDIOS_DeInit
or HAL_MDIOS_Init function.
When The compilation define USE_HAL_MDIOS_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registration feature is not available and all callbacks
are set to the corresponding weak functions.
