31.3 Memory map/register definition
The SPI has 8-bit registers to select SPI options, to control baud rate, to report SPI status,
to hold an SPI data match value, and for transmit/receive data.

31.3.1 SPI Status Register (SPIx_S)
This register contains read-only status bits.
When the FIFO is supported and enabled (FIFOMODE is 1): This register has four flags
that provide mechanisms to support an 8-byte FIFO mode: RNFULLF, TNEARF,
TXFULLF, and RFIFOEF. When the SPI is in 8-byte FIFO mode, the function of SPRF
