4.4.1.2 State 2: No Java Running, General Purpose I/O and I2C
The Java application is inactive. There is an AT parser with CSD on ASC0 as well as ASC1.
Up to ten I/0 pins are used as general purpose I/O plus a I2C interface. The pins are
configured by
at^scpin or at^sspi (refer to AT Command Set [3]).

4.4.1.3 State 3: No Java Running, General Purpose I/O and SPI
The Java application is inactive and there is an AT interface with CSD on ASC0 as well as
ASC1. There is an SPI interface as well at ten I/0 pins that can be used for general purpose
I/O. The pins are configured with
at^scpin or at^sspi (refer to AT Command Set [3]).

4.4.1.4 State 4: Default – Java Application Active
The Java application is active and ASC1 is used as System.out and the Java instance of the
RS-232 serial interface is connected to ASC0. Java instances of AT commands are
connected to the available AT parsers. The Java application is activated with at^sjra (refer to
AT Command Set [3]) or autostart.
