Clock select
IR enable (see
Reserved; set to ‘0’.
Loop-back. Enable the local loop-back mode (diagnostics). In this mode the
transmitter output (TX) and the receiver input (RX), CTS, DSR, CD, and RI
are disconnected from the SC16C652B I/O pins. Internally the modem data
and control pins are connected into a loop-back data configuration (see
Figure
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.
OP2/INT enable
(OP1). OP1A/OP1B are not available as an external signal in the
SC16C652B. This bit is instead used in the Loop-back mode only. In the
Loop-back mode, this bit is used to write the state of the modem RI interface
signal.

Rev. 04 — 1 September 2005
logic 0 = divide-by-1 clock input
logic 1 = divide-by-4 clock input
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.
logic 0 = disable Loop-back mode (normal default condition)
logic 1 = enable local Loop-back mode (diagnostics)
logic 0 = forces INT (A, B) outputs to the 3-state mode and sets OP2 to a
logic 1 (normal default condition)
logic 1 = forces the INT (A, B) outputs to the active mode and sets OP2 to
a logic 0
logic 0 = force RTS output to a logic 1 (normal default condition)
logic 1 = force RTS output to a logic 0
logic 0 = force DTR output to a logic 1 (normal default condition)
logic 1 = force DTR output to a logic 0
