Description
Serial Data Out 1.
This output sends serial data to the
communications link. This signal is set to a marking state (logic 1)
after a Master Reset operation or when the device is in one of the
Infrared communications modes.

Clear to Send 2 #.
When low, indicates that the MODEM or Data
Set is ready to accept data. The CTS# signal is a MODEM status
input whose condition can be tested by reading the MSR register.
Data Carrier Detect 2 # .
When low, indicates that the MODEM or
Data Set has detected a carrier. The DCD# signal is a MODEM
status input whose condition can be tested by reading the MSR
register.
Data Set Ready 2 #.
When low, indicates that the MODEM or Data
Set is ready to establish a communications link. The DSR# signal is
a MODEM status input whose condition can be tested by reading the
MSR register.
Data Terminal Ready 2 # / KBC Enable.
The default function of this pin is Data Terminal Ready 2 #. DTR#
is used to indicate to the MODEM or Data Set that the device is
ready to exchange data. DTR# is activated by setting the
appropriate bit in the MCR register to 1. After a Master Reset
operation or during Loop mode, DTR# is set to its inactive state.
The second function of this pin is the power-on strapping of KBC
(LDN 4) enable. This pin is weak pull-up internally.
Ring Indicator 2 #.
When low, indicates that a telephone ring signal
has been received by the MODEM. The RI# signal is a MODEM
status input whose condition can be tested by reading the MSR
register.
Request to Send 2 # / KBC Internal ROM Selected
The default function of this pin is Request To Send 2 #. When low,
this output indicates to the MODEM or Data Set that the device is
ready to send data. RTS# is activated by setting the appropriate bit
in the MCR register to 1. After a Master Reset operation or during
Loop mode, RTS# is set to its inactive state.
The second function of this pin is the power-on strapping of KBC
intrusion ROM select. When high (default), the internal ROM is
selected. When low, the external ROM is selected. This pin is
weak pull-up internally.
Serial Data In 2.
This input receives serial data from the
communications link.
Serial Data Out 2.
This output sends serial data to the
communications link. This signal is set to a marking state (logic 1)
after a Master Reset operation or when the device is in one of the
Infrared communications modes.
