/*****************************************************************************************
*
* I2C State Monitoring Functions
*
****************************************************************************************
* This I2C driver provides three different ways for I2C state monitoring
* profit the application requirements and constraints:
*
*
* a) First way:
* Using I2C_CheckEvent() function:
* It compares the status registers (STARR1 and STAR2) content to a given event
* (can be the combination of more flags).
* If the current status registers includes the given flags will return SUCCESS.
* and if the current status registers miss flags will returns ERROR.
* - 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
* (CH64xRM).
* - It is also suitable for users who need to define their own events.
* - Limitations:
* - If an error occurs besides to the monitored error,
* the I2C_CheckEvent() function may return SUCCESS despite the communication
* in corrupted state. it is suggeted to use error interrupts to monitor the error
* events and handle them in IRQ handler.
*
*
* Note:
* The following functions are recommended for error management: :
* - I2C_ITConfig() main function of configure and enable the error interrupts.
* - I2Cx_ER_IRQHandler() will be called when the error interrupt happen.
* Where x is the peripheral instance (I2C1, I2C2 ...)
* - I2Cx_ER_IRQHandler() will call I2C_GetFlagStatus() or I2C_GetITStatus() functions
* to determine which error occurred.
* - I2C_ClearFlag() \ I2C_ClearITPendingBit() \ I2C_SoftwareResetCmd()
* \ I2C_GenerateStop() will be use to clear the error flag and source,
* and return to correct communication status.
*
*
* b) Second way:
* Using the function to get a single word(uint32_t) composed of status register 1 and register 2.
* (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
* don't have the limitations of I2C_GetFlagStatus() function .
* The returned value could be compared to events already defined in the
* library (ch64x_i2c.h) or to custom values defined by user.
* - This function can be used to monitor the status of multiple flags simultaneously.
* - Contrary to the I2C_CheckEvent () function, this function can choose the time to
* accept the event according to the user's needs (when all event flags are set and
* no other flags are set, or only when the required flags are set)
*
* - 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).
*
*
* c) Third way:
* Using the function I2C_GetFlagStatus() get the status of
* one single flag .
* - 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 .
*
* - Limitations:
* - Call this function to access the status register. Some flag bits may be cleared.
* - Function may need to be called twice or more in order to monitor one single event.
