Busy flag This flag is set and cleared by hardware. Note: The BSY flag must be used with caution: refer to and .
CRC error flag Note: This flag is set by hardware and cleared by software writing 0. This bit is not used in I2S mode.
Frame format error This flag is used for SPI in TI slave mode and I2S slave mode. Refer to error flags and . This flag is set by hardware and reset when SPI_SR is read by software.
FIFO reception level These bits are set and cleared by hardware. Note: These bits are not used in I²S mode and in SPI receive-only mode while CRC calculation is enabled.
FIFO transmission level These bits are set and cleared by hardware. Note: This bit is not used in I2S mode.
Mode fault This flag is set by hardware and reset by a software sequence. Refer to (MODF) on page 1031 for the software sequence. Note: This bit is not used in I2S mode.
Overrun flag This flag is set by hardware and reset by a software sequence. Refer to page 1057 for the software sequence.
Receive buffer not empty
Transmit buffer empty
