0, then reading the UART Receive Data Register clears this bit.
0 = No overrun error occurred.
1 = An overrun error occurred.
FE—Framing Error
This bit indicates that a framing error (no STOP bit following data reception) was
detected. Reading the UART Receive Data Register clears this bit.
0 = No framing error occurred.
1 = A framing error occurred.
BRKD—Break Detect
This bit indicates that a break occurred. If the data bits, parity/multiprocessor bit, and
STOP bit(s) are all zeros then this bit is set to 1. Reading the UART Receive Data Register
clears this bit.
0 = No break occurred.
1 = A break occurred.
TDRE—Transmitter Data Register Empty
This bit indicates that the UART Transmit Data Register is empty and ready for additional
data. Writing to the UART Transmit Data Register resets this bit.
0 = Do not write to the UART Transmit Data Register.
1 = The UART Transmit Data Register is ready to receive an additional byte to be
TXE—Transmitter Empty
This bit indicates that the transmit shift register is empty and character transmission
is finished.
0 = Data is currently transmitting.
1 = Transmission is complete.
CTS—CTS Signal
When this bit is read it returns the level of the CTS signal.
This register contains multiprocessor control and status bits.
