SC16C852SV
Dual UART with 128-byte FIFOs, IrDA, and XScale VLIO bus interface
7.6 Modem Control Register (MCR)
This register controls the interface with the modem or a peripheral device.

Modem Control Register bits description
Symbol Description
MCR[7]
Clock select
logic 0 = divide-by-1 clock input
logic 1 = divide-by-4 clock input
MCR[6]
IR enable (see
Figure 15
).
logic 0 = enable the standard modem receive and transmit input/output interface
(normal default condition)
logic 1 = enable infrared IrDA receive and transmit inputs/outputs. While in this
mode, the TX/RX output/inputs are routed to the infrared encoder/decoder. The
data input and output levels will conform to the IrDA infrared interface
requirement. As such, while in this mode, the infrared TX output will be a logic 0
during idle data conditions.
MCR[5]
Reserved; set to ‘0’.
MCR[4]
Loopback. Enable the local Loopback mode (diagnostics). In this mode the
transmitter output (TX) and the receiver input (RX), CTS, DSR, CD, and RI are
disconnected from the SC16C852SV I/O pins. Internally the modem data and
control pins are connected into a loopback data configuration (see
Figure 7
). In
this mode, the receiver and transmitter interrupts remain fully operational. The
Modem Control Interrupts are also operational, but the interrupts’ sources are
switched to the lower four bits of the Modem Control. Interrupts continue to be
controlled by the IER register.
logic 0 = disable Loopback mode (normal default condition)
logic 1 = enable local Loopback mode (diagnostics)
MCR[3]
OP2A/OP2B, INT enable
logic 0 = forces INT (A, B) outputs to the 3-state mode (normal default condition)
logic 1 = forces the INT (A, B) outputs to the active mode
In Loopback mode, this bit is used to write the state of the modem CD interface
signal.
MCR[2]
This bit is used in the Loopback mode only. In the Loopback mode, this bit is used
to write the state of the modem RI interface signal.
MCR[1]
RTS
logic 0 = force RTS output to a logic 1 (normal default condition)
logic 1 = force RTS output to a logic 0
MCR[0]
DTR
logic 0 = force DTR output to a logic 1 (normal default condition)
logic 1 = force DTR output to a logic 0
