Receive Data Available (RDA)—
received data. Reading the Receive Data register clears this bit.
Physical Layer Error (PLE)—
match when a LIN slave or master is transmitting. This could be caused by a fault in the
physical layer or multiple devices driving the bus simultaneously. Reading the Status 0
register or the Receive Data register clears this bit.
Receive Data and Autobaud Overrun Error (OE)—
UART operation if a receive data overrun error occurs. This bit is also set during LIN
Slave autobaud if the BRG counter overflows before the end of the autobaud sequence,
indicating the receive activity was not an autobaud character or the master baud rate is too
slow. The ATB status bit will also be set in this case. This bit is cleared by reading the
Receive Data register.
Framing Error (FE)—
reception) was detected. Reading the Receive Data register clears this bit.
Break Detect (BRKD)—
at least 4 bit times occurred (Wake-up event) or (b) in Slave Wait Break state and a break
of at least 11 bit times occurred (Break event) or (c) in Slave Active state and a break of at
least 10 bit times occurs. Reading the Status 0 register or the Receive Data register clears
this bit.
Transmitter Data Register Empty (TDRE)—
register is empty and ready for additional data. Writing to the Transmit Data register resets
this bit.
Transmitter Empty (TXE)—
character transmission is finished.
LIN Slave Autobaud Complete (ATB)—
autobaud character is received. If the ABIEN bit is set in the LIN Control register, then a
receive interrupt is generated when this bit is set. Reading the Status 0 register clears this
bit. This bit will be 0 in LIN MASTER mode.
