Serial peripheral interface (SPI)
Bit 2 MSTR: Master selection
0: Slave configuration
1: Master configuration
Note: This bit should not be changed when communication is ongoing.
Not used in I 2 S mode
Bit1 CPOL: Clock polarity
0: CK to 0 when idle
1: CK to 1 when idle
Note: This bit should not be changed when communication is ongoing.
Not used in I 2 S mode
Bit 0 CPHA: Clock phase
0: The first clock transition is the first data capture edge
1: The second clock transition is the first data capture edge
Note: This bit should not be changed when communication is ongoing.
Not used in I 2 S mode

Bits 15:8 Reserved. Forced to 0 by hardware.
Bit 7 TXEIE: Tx buffer empty interrupt enable
0: TXE interrupt masked
1: TXE interrupt not masked. Used to generate an interrupt request when the TXE flag is set.
Note: To function correctly, the TXEIE and TXDMAEN bits should not be set at the same time.
Bit 6 RXNEIE: RX buffer not empty interrupt enable
0: RXNE interrupt masked
1: RXNE interrupt not masked. Used to generate an interrupt request when the RXNE flag is set.
Note: To function correctly, the RXNEIE and RXDMAEN bits should not be set at the same time.
Bit 5 ERRIE: Error interrupt enable
This bit controls the generation of an interrupt when an error condition occurs (CRCERR, OVR,
MODF in SPI mode and UDR, OVR in I 2 S mode).
0: Error interrupt is masked
1: Error interrupt is enabled.
Bits 4:3 Reserved. Forced to 0 by hardware.
