CRC calculation
A CRC calculator has been implemented for communication reliability. Separate CRC
calculators are implemented for transmitted data and received data. The CRC is calculated
using a programmable polynomial serially on each bit. The CRC is calculated on the
sampling clock edge defined by the CPHA and CPOL bits in the SPI_CR1 register.
CRC calculation is enabled by setting the CRCEN bit in the SPI_CR1 register. This action
resets the CRC registers (SPI_RXCRCR and SPI_TXCRCR). When the CRCNEXT bit in
SPI_CR2 is set, the SPI_TXCRCR value is transmitted at the end of the current byte
transmission.
If a byte is present in the Tx buffer, the CRC value is transmitted only after the transmission
of this byte. During the transmission of CRC, the CRC calculator is switched off and the
register value remains unchanged.
The CRCERR flag in the SPI_SR register is set if the value received in the shift register
during the SPI_TXCRCR value transmission does not match the SPI_RXCRCR value.
