7.3.4.7.6 RXFIFO Single Error Detection (SED)

The RXFIFO is protected with a parity bit. When a single bit error is detected during a read operation from the RXFIFO, the FLAG_RXFFSED, FLAG_RXFF, and FLAG_ERR are set to 1. The SPI controller can access the TLC6989 and write 1 to CLR_FLAG to clear the flags.
