Interface Descriptions 4.1 Overview This chapter covers information required to convert the DT2000-Dual into a subscriber unit application. In addition, some of the internal blocks of the device are described. Understanding these internal blocks is necessary for one to completely grasp the functions of the various interfaces. This chapter discusses the interface to the major blocks of the DT2000-Dual as shown in the following figure. These blocks include: n CODEC Interface n UART Interface n General Purpose Interface n User Interface n JTAG Interface Figure 4-1 Interface Block Diagram
AnyDATA.NET Inc. AnyTime AnyPlace Any Wireless Data SolutionTM All Rights Reserved. AD-2001-06-28 Ver 1.1 -17- 4.2 CODEC Interface The CODEC Interface is configured by internal and external figures. If the internal CODEC interface is used, additional glue logic is not necessary and the module…s very simple audio interface can be used. Otherwise if the internal CODEC interface is not used, an external CODEC is necessary to support the car-kit system. In this case, the module provides a PCM CODEC Interface. 4.2.1 Internal CODEC Interface The module contains analog audio interface circuitry. The contained audio interface supports all of the required conversation and amplification stages for the audio front end. The audio interface includes the amplification stages for both the microphone and earphone. The interface supports one single-ended microphone input and one single-ended earphone output. Table 4-1 Analog Audio Pinouts NAME DESCRIPTION CHARACTERISTIC MIC2 MIC Input Analog Input (Pin No. 58) * EAR_DET1 EAR/MIC Set Detect Logic Input (Pin No. 57) ** EAR_JACK+ Earphone Output Analog Output (Pin No. 60) GND_A Audio Ground Audio Ground (Pin No. 59) Note: * MIC2, along with being a microphone input, checks to see if the user has pressed the headset key, which allows the user to connect to or disconnect from a call. This pin is internally pulled high and is therefore normally in the high state. To activate this input and connect to or disconnect from a call, the user must set the MIC2 pin to a low state for 100ms to 200ms. ** EAR_DET1 checks to see if a headset has been connected to the ear-jack. When there is no headset connected to the ear-jack, the audio path is disconnected. When a headset is connected to the ear-jack an audio path is opened. To simulate a headset connected to the ear-jack, the user must apply a low signal to the EAR_DET1 pin for as long as the user wants the audio path to be kept open.

Pin No. 14 4.3 UART Interface 4.3.1 Primary UART interface The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that conforms to the RS-232 Interface protocol. The module provides 3.0V CMOS level outputs and 3.0V CMOS switching input levels. In addition, all inputs have a 5.0V tolerance, however 3.0V or 3.3V CMOS logic compatible signals are highly recommended. All the control signals of the RS-232 are active low, however the data signals, RXD and TXD, are active high. The UART has a 64 byte transmit (TX) FIFO and a 64 byte receive (RX) FIFO. The UART features hardware handshaking, programmable data sizes, programmable stop bits, and odd, even, no parity. The UART operates at a maximum bit rate of 115.2kbps.

It is strongly recommended for the user to have the following secondary UART pins connected to an extra connector or to test points, in order to easily troubleshoot any problems with the module.

Each GPIO pin can be configured as an input interrupt source. In addition, some GPIO pins can be used as output control pins from the module. The user can define these pins properly as follows.

The first type will reset the MSM and the memory and is performed when the user gives the AT command, AT+RESET, to the MSM. Another way to reset the module is by using the external hardware reset. This type of reset will reset the hardware as well as the MSM and the memory. The flash memory will be the only information that is kept. To perform an external hardware reset, make sure the module has powered on and is not in

Keep the external hardware reset pin low when the module is initializing as well as during normal operation. 4.6 LEDs The DT2000-Dual can indicate its current status through three pins. These three pins can be connected to LEDs to more quickly and easily determine the status of the module. The SMS LED indicates to the user if there is a SMS message or a voicemail message. If there is a SMS message or a voicemail message, the SMS LED will turn on. After the user has read the SMS message or listened to the voicemail message, the SMS LED turns off. Shortly after the module has been turned on, the Idle LED should turn on indicating that the module is in-service. This means that the module is within the range of the base station and is able to receive a signal from the base station. When the module is in traffic or conversation stage, the Busy LED is on.
