0
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 0s 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. This signal is active Low.
This register contains multiprocessor control and status bits.
Reserved—Must be 0.
NEWFRM—Status bit denoting the start of a new frame. Reading the UART Receive
Data register resets this bit to 0.
0 = The current byte is not the first data byte of a new frame.
1 = The current byte is the first data byte of a new frame.
