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 14
).
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]
Interrupt type.
logic 0 = CMOS output
logic 1 = open-source. A 300
Ω
to 500
Ω
pull-down resistor is required.
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 SC16C850V I/O pins. Internally the modem data and
control pins are connected into a loopback data configuration (see
Figure 6
). 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]
OP2. This bit is used for internal Loopback mode only. In Loopback mode, this
bit is used to write the state of the modem CD interface signal.
MCR[2]
OP1. This bit is used for internal Loopback mode only. In 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
