When auto-flow is enabled, the UART is not allowed to receive data until the UART asserts /RTS to external device. When the number of bytes in the RX FIFO equals the value of RTS_TRI_LEV (UA_FCR [19:16]), the /RTS is de- asserted. The UART sends data out when UART controller detects /CTS is asserted from external evice. If a valid asserted /CTS is not detected the UART controller will not send data out. RT controllers also provides Serial IrDA (SIR, Serial Infrared) function (User must set Ir ( E ble ct n defines a short-range infrared asynchronous serial transmission mode with one start bit, 8 data bits, and 1 stop bit. The maximum data rate is 115.2 Kbps (half duplex). he an IrDA SIR Protocol encoder/decoder. The IrDA SIR protocol ha d receive data at the same time.

For NuMicro ™ NUC100/NUC120 Low Density, another alternate function of UART controllers is RS-485 9-bit mode functio TS pin or can program GPIO (PB.2 for RTS0 and PB.6 for RTS1) to implement the function by software. The RS-485 mode is selected by setting the UA_FUN_SEL register to select RS-485 function. The RS-485 driver control is implemented using the RTS control signal from an asynchronous serial port to enable the RS-485 driver. In RS-485 mode, many characteristics of the RX and TX are same as UART. d The UA DA_EN UA_FUN_S L [1]) to ena IrDA fun ion). The SIR specificatio T IrDA SIR block contains is ica lf-duplex only.
