Hii can anyone help me how to use this smbus feature with example and what shuold be selected for xferoptions ......HAL_SMBUS_Master_Transmit_IT(SMBUS_HandleTypeDef *hsmbus, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint32_t XferOptions)

[TDK]

One of these:

#define IS_SMBUS_TRANSFER_OPTIONS_REQUEST(REQUEST) (((REQUEST) == SMBUS_FIRST_FRAME)                   || \
                                                    ((REQUEST) == SMBUS_NEXT_FRAME)                    || \
                                                    ((REQUEST) == SMBUS_FIRST_AND_LAST_FRAME_NO_PEC)   || \
                                                    ((REQUEST) == SMBUS_LAST_FRAME_NO_PEC)             || \
                                                    ((REQUEST) == SMBUS_FIRST_AND_LAST_FRAME_WITH_PEC) || \
                                                    ((REQUEST) == SMBUS_LAST_FRAME_WITH_PEC))

Include your chip number.
