8.21 Enhanced Features Register (EFR)
This 8-bit register enables or disables the enhanced features of the UART. Table 31
shows the Enhanced Features Register bit settings.

RS-485 features
9.1 Auto RS-485 RTS control
Normally the RTS pin is controlled by MCR bit 1, or if hardware flow control is enabled, the
logic state of the RTS pin is controlled by the hardware flow control circuitry. EFCR
register bit 4 will take the precedence over the other two modes; once this bit is set, the
transmitter will control the state of the RTS pin. The transmitter automatically asserts the
RTS pin (logic 0) once the host writes data to the transmit FIFO, and de-asserts RTS pin
(logic 1) once the last bit of the data has been transmitted.
To use the auto RS-485 RTS mode the software would have to disable the hardware flow
control function.
9.2 RS-485 RTS output inversion
EFCR bit 5 reverses the polarity of the RTS pin if the UART is in auto RS-485 RTS mode.
When the transmitter has data to be sent it de-asserts the RTS pin (logic 1), and when the
last bit of the data has been sent out the transmitter asserts the RTS pin (logic 0).

Enhanced Features Register bits description
Bit
Symbol
Description
7
EFR[7]
CTS flow control enable.
logic 0 = CTS flow control is disabled (normal default condition)
logic 1 = CTS flow control is enabled. Transmission will stop when a
HIGH signal is detected on the CTS pin.
6
EFR[6]
RTS flow control enable.
logic 0 = RTS flow control is disabled (normal default condition)
logic 1 = RTS flow control is enabled. The RTS pin goes HIGH when
the receiver FIFO halt trigger level TCR[3:0] is reached, and goes
LOW when the receiver FIFO resume transmission trigger level
TCR[7:4] is reached.
5
EFR[5]
Special character detect.
logic 0 = special character detect disabled (normal default condition)
logic 1 = special character detect enabled. Received data is compared
with Xoff2 data. If a match occurs, the received data is transferred to
FIFO and IIR[4] is set to a logical 1 to indicate a special character has
been detected.
4
EFR[4]
Enhanced functions enable bit.
logic 0 = disables enhanced functions and writing to IER[7:4],
FCR[5:4], MCR[7:5].
logic 1 = enables the enhanced function IER[7:4], FCR[5:4], and
MCR[7:5] so that they can be modified.
3:0
EFR[3:0]
Combinations of software flow control can be selected by programming
these bits. See Table 3 “Software flow control options (EFR[3:0])”.
