XR21V1412
2-CH FULL-SPEED USB UART
ERROR_STATUS[4]: Framing Error
ERROR_STATUS[5]: Parity Error
ERROR_STATUS[6]: Overrun Error
ERROR_STATUS[7]: Break Status
Writing a non-zero value to this register causes a break condition to be generated continuously until the
register is cleared. If data is being shifted out of the TX pin, the data will be completely shifted out before the
break condition is generated.
XCVR_EN_DELAY[3:0]: Turn-around delay
This is the number of bit times to wait before changing the direction of the transceiver from transmit to receive
when half-duplex mode is enabled.
XCVR_EN_DELAY[3:0]: Reserved
These bits are reserved and should be ’0’.

Logic 0 = No framing error
Logic 1 = A framing error has been detected (clears after read). A framing error occurs when a stop bit is not
present when it is expected.
Logic 0 = No parity error
Logic 1 = A parity error has been detected (clears after read).
Logic 0 = No overrun error
Logic 1 = An overrun error has been detected (clears after read). An overrun error occurs when the RX FIFO
is full and another byte of data is received.
Logic 0 = Break condition is no longer present.
Logic 1 = Break condition is currently being detected.
