                                                    & ((__FLAG__) & I2S_FLAG_MASK)) == ((__FLAG__) & I2S_FLAG_MASK))\
                                                  ? SET : RESET)

Check whether the specified SPI flag is set or not.

Parameters:

__SR__	copy of I2S SR register.
__FLAG__	specifies the flag to check. This parameter can be one of the following values: I2S_FLAG_RXP : Rx-Packet available flag I2S_FLAG_TXP : Tx-Packet space available flag I2S_FLAG_UDR : Underrun flag I2S_FLAG_OVR : Overrun flag I2S_FLAG_FRE : TI mode frame format error flag

Return values:
