SPI_CHECK_FLAG macro

Check whether the specified SPI flag is set or not.

Syntax

#define SPI_CHECK_FLAG(__SR__, __FLAG__) ((((__SR__) & ((__FLAG__) & SPI_FLAG_MASK)) == \     ((__FLAG__) & SPI_FLAG_MASK)) ? SET : RESET)

Arguments

__SR__

copy of SPI SR register.

__FLAG__

specifies the flag to check. This parameter can be one of the following values: @arg SPI_FLAG_RXNE: Receive buffer not empty flag @arg SPI_FLAG_TXE: Transmit buffer empty flag @arg SPI_FLAG_CRCERR: CRC error flag @arg SPI_FLAG_MODF: Mode fault flag @arg SPI_FLAG_OVR: Overrun flag @arg SPI_FLAG_BSY: Busy flag @arg SPI_FLAG_FRE: Frame format error flag

Return value

SET or RESET.
