USE_HAL_I2C_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_I2C_RegisterCallback() or HAL_I2C_RegisterAddrCallback() + to register an interrupt callback. + [..] + Function HAL_I2C_RegisterCallback() allows to register following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+)

reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) MemTxCpltCallback : callback for Memory transmission end of transfer. + (+) MemRxCpltCallback : callback for Memory reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + [..] + For specific callback AddrCallback use dedicated register callbacks : HAL_I2C_RegisterAddrCallback(). + [..] + Use function HAL_I2C_UnRegisterCallback to reset a callback to the default + weak function. +
