0 = No parity error has occurred.
1 = A parity error has occurred.
OE—Overrun Error
This bit indicates that an overrun error has occurred. An overrun occurs when new data is
received and the UART Receive Data register has not been read. If the RDA bit is reset to
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 transmit-
ted.
TXE—Transmitter Empty
This bit indicates that the transmit shift register is empty and character transmission is fin-
ished.
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.
