* 2) Master Transmitter mode: The master has to send data (I2C_SendData()

* - EV8_2 means that the data has been physically shifted out and output
* on the bus.
* In most cases, using EV8 is sufficient for the application.

* EV8_2 is also more suitable than EV8 for testing on the last data transmission
* (before Stop condition generation).

* managed before the current byte end of transfer, then user may check on EV7
* and BTF flag at the same time (ie. (I2C_EVENT_MASTER_BYTE_RECEIVED | I2C_FLAG_BTF)).

* I2C_EVENT_SLAVE_BYTE_TRANSMITTING are similar. The second one can optionally be
* used when the user software doesn't guarantee the EV3 is managed before the
* current byte end of transfer.
* - EV3_2: When the master sends a NACK in order to tell slave that data transmission
* shall end (before sending the STOP condition). In this case slave has to stop sending
* data bytes and expect a Stop condition on the bus.
*
* @note In case the user software does not guarantee that the event EV2 is
* managed before the current byte end of transfer, then user may check on EV2
* and BTF flag at the same time (ie. (I2C_EVENT_SLAVE_BYTE_RECEIVED | I2C_FLAG_BTF)).
* In this case the communication may be slower.

****************************************************************************************
*
* I2C State Monitoring Functions
*
****************************************************************************************
* This I2C driver provides three different ways for I2C state monitoring
* depending on the application requirements and constraints:
*
*
* 1) Basic state monitoring:
* Using I2C_CheckEvent() function:
* It compares the status registers (SR1 and SR2) content to a given event
* (can be the combination of one or more flags).
* It returns SUCCESS if the current status includes the given flags
* and returns ERROR if one or more flags are missing in the current status.
* - When to use:
* - This function is suitable for most applications as well as for startup
* activity since the events are fully described in the product reference manual
* (RM0008).
* - It is also suitable for users who need to define their own events.
* - Limitations:
* - If an error occurs (ie. error flags are set besides to the monitored flags),
* the I2C_CheckEvent() function may return SUCCESS despite the communication
* hold or corrupted real state.
* In this case, it is advised to use error interrupts to monitor the error
* events and handle them in the interrupt IRQ handler.
*
* @note
* For error management, it is advised to use the following functions:
* - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
* - I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
* Where x is the peripheral instance (I2C1, I2C2 ...)
* - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into I2Cx_ER_IRQHandler()
* in order to determine which error occurred.
* - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
* and/or I2C_GenerateStop() in order to clear the error flag and source,
* and return to correct communication status.
*
*
* 2) Advanced state monitoring:
* Using the function I2C_GetLastEvent() which returns the image of both status
* registers in a single word (uint32_t) (Status Register 2 value is shifted left
* by 16 bits and concatenated to Status Register 1).
* - When to use:
* - This function is suitable for the same applications above but it allows to
* overcome the limitations of I2C_GetFlagStatus() function (see below).
* The returned value could be compared to events already defined in the
* library (ch32f10x_i2c.h) or to custom values defined by user.
* - This function is suitable when multiple flags are monitored at the same time.
* - At the opposite of I2C_CheckEvent() function, this function allows user to
* choose when an event is accepted (when all events flags are set and no
* other flags are set or just when the needed flags are set like
* I2C_CheckEvent() function).
* - Limitations:
* - User may need to define his own events.
* - Same remark concerning the error management is applicable for this
* function if user decides to check only regular communication flags (and
* ignores error flags).
*
*
* 3) Flag-based state monitoring:
* Using the function I2C_GetFlagStatus() which simply returns the status of
* one single flag (ie. I2C_FLAG_RXNE ...).
* - When to use:
* - This function could be used for specific applications or in debug phase.
* - It is suitable when only one flag checking is needed (most I2C events
* are monitored through multiple flags).
* - Limitations:
* - When calling this function, the Status register is accessed. Some flags are
* cleared when the status register is accessed. So checking the status
* of one Flag, may clear other ones.
* - Function may need to be called twice or more in order to monitor one
* single event.

*
* I2C State Monitoring Functions
*
****************************************************************************************
* This I2C driver provides three different ways for I2C state monitoring
* depending on the application requirements and constraints:
*
*
* 1) Basic state monitoring:
* Using I2C_CheckEvent() function:
* It compares the status registers (SR1 and SR2) content to a given event
* (can be the combination of one or more flags).
* It returns SUCCESS if the current status includes the given flags
* and returns ERROR if one or more flags are missing in the current status.
* - When to use:
* - This function is suitable for most applications as well as for startup
* activity since the events are fully described in the product reference manual
* (RM0008).
* - It is also suitable for users who need to define their own events.
* - Limitations:
* - If an error occurs (ie. error flags are set besides to the monitored flags),
* the I2C_CheckEvent() function may return SUCCESS despite the communication
* hold or corrupted real state.
* In this case, it is advised to use error interrupts to monitor the error
* events and handle them in the interrupt IRQ handler.
*
* @note
* For error management, it is advised to use the following functions:
* - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
* - I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
* Where x is the peripheral instance (I2C1, I2C2 ...)
* - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into I2Cx_ER_IRQHandler()
* in order to determine which error occured.
* - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
* and/or I2C_GenerateStop() in order to clear the error flag and source,
* and return to correct communication status.
*
*
* 2) Advanced state monitoring:
* Using the function I2C_GetLastEvent() which returns the image of both status
* registers in a single word (uint32_t) (Status Register 2 value is shifted left
* by 16 bits and concatenated to Status Register 1).
* - When to use:
* - This function is suitable for the same applications above but it allows to
* overcome the mentioned limitation of I2C_GetFlagStatus() function.
* The returned value could be compared to events already defined in the
* library (ch32f10x_i2c.h) or to custom values defined by user.
* - This function is suitable when multiple flags are monitored at the same time.
* - At the opposite of I2C_CheckEvent() function, this function allows user to
* choose when an event is accepted (when all events flags are set and no
* other flags are set or just when the needed flags are set like
* I2C_CheckEvent() function).
* - Limitations:
* - User may need to define his own events.
* - Same remark concerning the error management is applicable for this
* function if user decides to check only regular communication flags (and
* ignores error flags).
*
*
* 3) Flag-based state monitoring:
* Using the function I2C_GetFlagStatus() which simply returns the status of
* one single flag (ie. I2C_FLAG_RXNE ...).
* - When to use:
* - This function could be used for specific applications or in debug phase.
* - It is suitable when only one flag checking is needed (most I2C events
* are monitored through multiple flags).
* - Limitations:
* - When calling this function, the Status register is accessed. Some flags are
* cleared when the status register is accessed. So checking the status
* of one Flag, may clear other ones.
* - Function may need to be called twice or more in order to monitor one
* single event.
*
* For detailed description of Events, please refer to section I2C_Events in
* ch32f10x_i2c.h file.
