UART/IrDA/CIR Register Manual
Bits Field Name Description Type Reset
0x1: Auto-CTS flow control is enabled; transmission is
halted when the nCTS pin is high (inactive).
6 AUTO_RTS_EN Auto-RTS enable bit (UART mode only) RW 0
0x0: Normal operation
0x1: Auto-RTS flow control is enabled; nRTS pin goes
high (inactive) when the receiver FIFO HALT
trigger level,
TCR_REG [3:0], is reached and goes
low (active) when the receiver FIFO RESTORE
transmission trigger level is reached.
5 SPEC_CHAR (UART mode only) Special character detect RW 0
0x0: Normal operation
0x1: Special character detect enable. Received data is
compared with XOFF2 data. If a match occurs, the
received data is transferred to RX FIFO and
IIR_REG bit 4 is set to 1 to indicate that a special
character was detected.
4 ENHANCED_EN Enhanced functions write enable bit RW 0
0x0: Disables writing to IER_REG bits [7:4], FCR_REG
bits [5:4], and MCR_REG bits [7:5]
0x1: Enables writing to IER_REG bits [7:4], FCR_REG
bits [5:4], and MCR_REG bits [7:5]
3:0 SW_FLOW_ Combinations of software flow control can be selected by RW 0x0
CONTROL programming bit [3:0].
See Table 19-32 . In IrDA mode, bits [1:0] select IR
address to check. See Section 19.2.5.2.1.7 , IR Address
Checking.
