RXD—Receive Data

LIN-UART receiver data byte from the RXD pin

LIN-UART Status 0 Register

The LIN-UART Status 0 Register identifies the current LIN-UART operating configura-

tion and status. Table 68 describes the Status 0 Register for standard UART mode. Table

69, which follows on page 132, describes the Status0 Register for LIN mode. A more

detailed discussion of each bit follows each table.

Receive Data Available (RDA).

This bit indicates that the LIN-UART Receive Data Reg-

ister has received data. Reading the LIN-UART Receive Data Register clears this bit.

Parity Error (PE).

This bit indicates that a parity error has occurred. Reading the Receive

Data Register clears this bit.

Overrun Error (OE).

This bit indicates that an overrun error has occurred. An overrun

occurs when new data is received and the Receive Data Register has not been read. Read-

ing the Receive Data Register clears this bit.

Framing Error (FE).

This bit indicates that a framing error (no STOP bit following data

reception) was detected. Reading the Receive Data Register clears this bit.

Break Detect (BRKD).

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

Receive Data Register clears this bit.

Transmitter Data Register Empty (TDRE).

This bit indicates that the Transmit Data

resets this bit.

Transmitter Empty (TXE).

This bit indicates that the transmit shift register is empty and

character transmission is finished.

Clear To Send Signal (CTS).

When this bit is read it returns the level of the CTS signal.

If LBEN = 1, the CTS input signal is replaced by the internal Receive Data Available sig-
