3 USING THE EZ-KIT LITE 3.1 Overview This chapter provides specific information to assist you with developing your programs for the ADSP-2191 EZ-KIT Lite board. This information appears in the following sections: • EZ-KIT Lite License Restrictions (Section 3.2) Describes the restrictions of the EZ-KIT Lite demo license. •...
3.2 EZ-KIT Lite License Restrictions The license that is shipped with the EZ-KIT Lite imposes the following restrictions: • Program Memory (PM) space is limited to 8K words (1/4 of the ADSP- 2191 PM space) • No connections to Simulator or Emulator sessions are allowed. 3.3 Memory Map The ADSP-2191 has 32k words of internal SRAM that can be used for program storage or data storage.
3.4 Using the Programmable Flag Pins The ADSP-2191 has 8 asynchronous programmable flag I/O pins (PF0-7) that let you interact with the running program. Data pins 8-15 can also be used as Programmable Flag pins depending on the configuration of the DSP. During reset, the flag pins (PF0-7) are used to set the multiplication factor, which sets the core clock frequency.
3.6 Using the Flash Programmer Utility The ADSP-2191 EZ-KIT Lite evaluation system includes a flash programmer utility. The utility allows you to program the flash on the EZ-KIT. This utility must be installed separately from the debug software. To install the utility, insert the EZ-KIT CD-ROM and follow the steps in the installation wizard.
4 EZ-KIT LITE HARDWARE REFERENCE 4.1 Overview This chapter describes the hardware design of the ADSP-2191 EZ-KIT Lite board. The following topics are covered: • System Architecture (Section 4.2) Describes the configuration of the DSP as well as all a description of how all of the components on the board interface with the DSP.
4.2 System Architecture The EZ-KIT Lite has been designed to provide access to all of the capabilities of the ADSP-2191 DSP. This section will describe the DSP’s configuration on the EZ-KIT Lite board. JTAG Host Header Connector Connectors D[7:0] 8 Bit Flash A[18:0] AD[15:0] Memory...
The input clock to the DSP is a 16MHz through-hole oscillator. Footprints are provided on the board for a surface-mount oscillator or a through-hole crystal. The speed at which the core operates is determined by the configuration of the multiplication factor switch (SW4) at reset and the state of the BYPASS jumper (JP7).
4.2.4 SPORT1 – Telephony Interface SPORT1 is connected to the AD1803 telephony codec (U11). The telephony interface provided by the AD1803 allows the DSP to act as a modem on a standard telephone line. Four of the general-purpose pins of the AD1803 are used.
The JTAG emulation port allows an emulator to access the DSP’s internal and external memory, as well as the special function registers. See section 4.5.5 more information about the JTAG connector. To learn more about available emulators, contact Analog Devices. See section for information about contacting Analog Devices.
4.3.1 Audio Input Select (JP1) The audio input jack (P3) can be connected to the MIC1 or the LINEIN channel of the AD1885 codec. When the JP1 jumpers are between pins 1 and 3 and between pins 2 and 4, P3 connects to the mono MIC1 channel of the AD1885 codec.
4.3.4 Audio Codec Disable (JP4) Placing a jumper between pins 2 and 3 of JP4 places the AD1885 into reset and isolate its serial port outputs, which are connected to the DSP. When a jumper is between pins 1 and 2 of JP4, the AD1885 is reset on power up, or can be reset using PF7 of the DSP.
4.3.7 DSP Clock Multiplier Select Switch (SW4) The core clock speed of the DSP after reset is set by the positions of the DSP Clock Multiplier Select Switch (SW4) at reset. Table 4-4 shows the default setting for SW4. This will produce a 10x multiplication factor, resulting in a 160MHz core clock speed.
4.4 LEDs and Push Buttons This section describes the function of all the LEDs and push buttons. Figure 4-4 shows the location of all the LEDs and push buttons. TX (LED4) RX (LED5) Phone (LED6) PF3-0 (LED11-8) USB Monitor (LED7) Reset PB (SW1) PF5 (SW2) Reset LED (LED2)
When LED3 is lit, the ADSP-2191 (U1) is being reset. The USB interface resets the ADSP-2191 during USB communication initialization. 4.4.3 Telephony LEDs (LED4, LED5, LED6) Three LEDs connect to the AD1803 telephony codec. LED4 indicates that the AD1803 is transmitting serial data to the DSP’s SPORT1. LED5 indicates that the AD1803 is receiving serial data from the DSP.
4.4.7 Programmable Flag Push Buttons (SW2, SW3) Two push buttons are provided for general-purpose user input. SW2 and SW3 connect to the DSP’s programmable flag pins. The push buttons are active high and when pressed send a high (1) to the DSP. Refer to section for more information about the use of the programmable flags when programming the DSP.
4.5 Connectors This section describes the function of the connectors and gives information about mating connectors. The following figure shows the locations of the connectors.
