– Transmits parity bit.
– Checks parity of received data byte.
 LIN break generation and detection.
 IrDA support.
 Synchronous mode and transmitter clock output for synchronous transmission.
 ISO 7816-3 compliant smartcard interface.
– Character mode (T=0).
– Block mode (T=1).
– Direct and inverse convention.
 Multiprocessor communication.
– Enter into mute mode if address match does not occur.
– Wake up from mute mode by idle line or address match detection.
 Support for ModBus communication.
– Timeout feature.
– CR/LF character recognition.
 Wake up from deep-sleep mode.
– By standard RBNE interrupt.
– By WUF interrupt.
 Various status flags
– Flags for transfer detection: Receive buffer not empty (RBNE), receive FIFO full
(RFF), Transmit buffer empty (TBE), transfer complete (TC).
– Flags for error detection: overrun error (ORERR), noise error (NERR), frame error
(FERR) and parity error (PERR).
– Flag for hardware flow control: CTS changes (CTSF).
– Flag for LIN mode: LIN break detected (LBDF).
– Flag for multiprocessor communication: IDLE frame detected (IDLEF).
– Flag for ModBus communication: address/character match (AMF) and receiver
timeout (RTF).
– Flags for smartcard block mode: end of block (EBF) and receiver timeout (RTF).
– Wakeup from deep-sleep mode flag.
– Interrupt occurs at these events when the corresponding interrupt enable bits are
set.
While USART0 is fully implemented, USART1 is only partially implemented with the following
features not supported.
 Smartcard mode.
 IrDA SIR ENDEC block.
 LIN mode.
 Dual clock domain and wakeup from deep-sleep mode.
 Receiver timeout interrupt.
 ModBus communication.
