Bits 15:0 TxCRC[15:0]: Tx CRC register
When CRC calculation is enabled, the TxCRC[7:0] bits contain the computed CRC value of the
subsequently transmitted bytes. This register is reset when the CRCEN bit of SPI_CR1 is written to
1. The CRC is calculated serially using the polynomial programmed in the SPI_CRCPR register.
Only the 8 LSB bits are considered when the data frame format is set to be 8-bit data (DFF bit of
SPI_CR1 is cleared). CRC calculation is done based on CRC8.
The entire 16-bits of this register are considered when a 16-bit data frame format is selected (DFF
bit of the SPI_CR1 register is set). CRC calculation is done based on CRC16 - CCITT standard.
Note: A read to this register when the BSY flag is set could return an incorrect value.
Not used for the I 2 S mode.
