SC16C850
2.5 to 3.3 V UART with 128-byte FIFOs and IrDA encoder/decoder
7.14 Enhanced Feature Register (EFR)
Enhanced features are enabled or disabled using this register.
Bits 0 through 4 provide single or dual character software flow control selection. When the
Xon1 and Xon2 and/or Xoff1 and Xoff2 modes are selected, the double 8-bit words are
concatenated into two sequential numbers.
Table 23.

Enhanced function control bits IER[7:4], ISR[5:4], FCR[5:4] and MCR[7:5].
Enhanced Feature Register bits description
Symbol
Description
EFR[7]
Automatic CTS flow control.
logic 0 = automatic CTS flow control is disabled (normal default condition)
logic 1 = enable automatic CTS flow control. Transmission will stop when
CTS goes to a logical 1. Transmission will resume when the CTS pin returns
to a logical 0.
EFR[6]
Automatic RTS flow control. Automatic RTS may be used for hardware flow
control by enabling EFR[6]. When Auto-RTS is selected, an interrupt will be
generated when the receive FIFO is filled to the programmed trigger level and
RTS will go to a logic 1 at the next trigger level. RTS will return to a logic 0 when
data is unloaded below the next lower trigger level (programmed trigger level 1).
The state of this register bit changes with the status of the hardware flow
control. RTS functions normally when hardware flow control is disabled.
logic 0 = automatic RTS flow control is disabled (normal default condition)
logic 1 = enable automatic RTS flow control
EFR[5]
Special Character Detect.
logic 0 = special character detect disabled (normal default condition)
logic 1 = special character detect enabled. The SC16C850 compares each
incoming receive character with Xoff2 data. If a match exists, the received
data will be transferred to FIFO and ISR[4] will be set to indicate detection of
special character. Bit 0 in the X-registers corresponds with the LSB bit for the
receive character. When this feature is enabled, the normal software flow
control must be disabled (EFR[3:0] must be set to a logic 0).
EFR[4]
Enhanced function control bit. The content of IER[7:4], ISR[5:4], FCR[5:4], and
MCR[7:5] can be modified and latched. After modifying any bits in the enhanced
registers, EFR[4] can be set to a logic 0 to latch the new values. This feature
prevents existing software from altering or overwriting the SC16C850 enhanced
functions.
logic 0 = disable/latch enhanced features
[1]
. (Normal default condition.)
logic 1 = enables the enhanced functions
[1]
.
EFR[3:0]
Cont-3:0 TX, RX control. Logic 0 or cleared is the default condition.
Combinations of software flow control can be selected by programming these
bits. See
Table 24
