15
Bits 15:8 Reserved. Forced to 0 by hardware.
Bit 2 SSOE: SS output enable
Bit 1 TXDMAEN: Tx buffer DMA enable
Bit 0 RXDMAEN: Rx buffer DMA enable
Bit 7 BSY: Busy flag
Bit 6 OVR: Overrun flag
Bit 5 MODF: Mode fault
Bit 4 CRCERR: CRC error flag
14
SPI status register (SPI_SR)
Address offset: 08h
Reset value: 0x0002
Note: Not used in I
Note: In master receiver-only mode (1-line bidirectional), it is forbidden to check the BSY flag.
Note: Not used in I
Note: Not used in I
0: SS output is disabled in master mode and the cell can work in multimaster configuration
1: SS output is enabled in master mode and when the cell is enabled. The cell cannot work in a
multimaster environment.
When this bit is set, the DMA request is made whenever the TXE flag is set.
0: Tx buffer DMA disabled
1: Tx buffer DMA enabled
When this bit is set, the DMA request is made whenever the RXNE flag is set.
0: Rx buffer DMA disabled
1: Rx buffer DMA enabled
0: SPI (or I2S) not busy
1: SPI (or I2S) is busy in communication or Tx buffer is not empty
This flag is set and cleared by hardware.
0: No overrun occurred
1: Overrun occurred
This flag is set by hardware and reset by a software sequence. Refer to
for the software sequence.
0: No mode fault occurred
1: Mode fault occurred
This flag is set by hardware and reset by a software sequence. Refer to
for the software sequence.
0: CRC value received matches the SPI_RXCRCR value
1: CRC value received does not match the SPI_RXCRCR value
This flag is set by hardware and cleared by software writing 0.
