6.2 Serial Interface Mode
The EIA-232-E asynchronous Serial Interface is supported to use 4 dedicated signal lines
( SRXD, STXD, SCTS and SRTS ) and 4 common signal lines ( CI, DTR DRS, and DCD ).
The Box modem for connect with the Serial port of PC, can be created to connect with the
EIA-232-E Driver/Receiver IC as shown in [ Figure 7 ]. Also, embedded serial modem can be
created to connect with serial port of Host CPU as shown in [ Figure 8 ].
* Not supported for voice processing function
[ Features ]
a) Support automatic configuration such as Automatic Speed Recognition, Automatic
Format Recognition.
b) Support 2400bps ~ 460.8Kbps. ( 2400, 4800, 7200, 9600, 14.4K, 19.2K, 38.4K, 57.6K,
76.8K, 115.2K, 230.4K, 460.8K )
c) Implement 32K bytes FIFO for Transmitting/Receiving Data, so that automatic flow
operation can be performed by FIFO condition.
* Refer “ MN195007 AT Command Specifications” for mode details of AT command.
