Developer Board and Interfaces Description
3.4.2 Communication Interfaces
The g20 Developer Board includes three serial interfaces:
•RS232
•USB
• SPI
The RS232 and USB ports are multiplexed within the g20, and therefore cannot be operated simultaneously. The default connection is RS232.
The USB and RS232 is not detected dynamically. The selected serial connection is determined by the USB cable connection at
power up. If the USB cable is connected (and the PC is on), then USB is selected. Otherwise, RS232 is selected.
The SPI RS232 interface is used for debugging.

3.4.2.1 RS232
The 9-pin, D-type RS232-1 serial port (J350) is the primary interface to the g20 UUT. The UUT RS232 signals are active-low
CMOS-level signals (0-2.7 V), which are converted by the Developer Board to standard RS232 levels for PC communications.

3.4.2.3 SPI
The 9-pin D-type RS232-2 serial port (J500) is connected to the g20 internal SPI bus. This interface is used to debug applications. On the Developer Board, the g20 SPI interface is converted to standard RS232 signals for PC communications. The
conversion process uses the RS232 interface as a second slave on the internal g20 SPI bus, and communicates with it as such.
SPI read and write operations are performed normally, using the CS and IRQ signals provided by the conversion circuit. The
IRQ signal is connected to a g20 IRQ pin.

3.4.3.4 Headset
The headset interface is designed as a portable phone audio interface, and is similar to a phone headset interface. The headset
connector (J440) includes a speaker, microphone and a detection signal. The speaker and microphone signals are directly
connected to the g20 audio signals.
The purpose of the detection circuit is to switch the g20 headset audio paths on and off, whenever a headset connection is
detected. Headset detection is made whenever a headset plug is inserted into the jack. This action disables the g20 microphone
and speaker, and routes the audio signals to the headset.

3.4.9 Host
An external application may communicate with the g20 through the host connector (J1) and control some or all of the g20's
functions. The host connector enables you to integrate the g20 into an application without installing the g20 inside the product.
The host connector operates in parallel with the developer board peripherals and enables an external application to share g20
resources with the developer board. You may select any g20 function to control externally, through the host connector, and allow
the developer board to control other functions.

You can connect an external application to the g20 Developer Board using a host interconnect flex cable and connecting it to
the host connector (J1). Connect the other end of the cable to the external application. The cable is an optional accessory.
All pin numbers and functions of the host connector are identical to those of the g20 UUT (P1) and the g20 diagnostic connector
(P100). For more information on the pins of the host connector, refer to “UUT Interface Connector” on page 27.
The following are guidelines for using the host connector:
• When using an external SIM card through the host connector, the developer board SIM card jumper (P110) must be disconnected and the SIM card tray should be empty.
• When using any of the serial communication channels (USB, RS232, SPI) through the host connector, the developer board
serial connectors should not be used.
• When using the IGN or WAKEUP functions through the host connector, the functions should be switched off on the developer board Dip switches.
• When using the analog audio channels through the host connector, disconnect all audio devices from the developer board.
• When using the PCM digital audio through the host connector, it is recommended to place the audio selection jumper (P420)
to analog audio mode.
• When connecting an external application that provides the power to the g20 and the Developer Board, remove any other
power sources from the Developer Board.
