Table 6-7 UART Baud Rate Setting Table
The UART0 and UART1 controllers support the auto-flow control function that uses two low-level
signals, /CTS (clear-to-send) and /RTS (request-to-send), to control the flow of data transfer
between the chip and external devices (e.g. Modem). 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
device. If a valid asserted /CTS is not detected the UART controller will not send data out.

The UART controllers also provides Serial IrDA (SIR, Serial Infrared) function (User must set
IrDA_EN (UA_FUN_SEL [1]) to enable IrDA function). The SIR specification defines a short-range
infrared asynchronous serial transmission mode with 1 start bit, 8 data bits, and 1 stop bit. The
maximum data rate supports up to 115.2 Kbps (half duplex). The IrDA SIR block contains an IrDA
