3 USING THE EZ-KIT LITE 3.1 Overview This chapter provides specific information to assist you with developing programs for the ADSP-21535 EZ-KIT Lite board. This information appears in the following sections: • EZ-KIT Lite License Restrictions (Section 3.
3.2 EZ-KIT Lite License Restrictions The license shipped with the EZ-KIT Lite imposes the following restrictions: • Internal Memory space is limited to 176 KB of the ADSP-21535 internal memory space • No connections to Simulator or Emulator sessions are allowed.
3.4 Using the SDRAM Interface In order to use the 4M x 32 bits (16 MB) of SDRAM memory, the three SDRAM control registers must be initialized. The following tab le shows the standard configuration for these registers when using the EZ-KIT Lite in the default configuration.

3.6 Using the Programmable Flag Pins The ADSP-21535 has 16 asynchronous Program mable Flag (PF) I/O pins. During reset PF0-PF9 function as inputs to th e internal PLL of the DSP. They are not valid until 120uS after reset. Table 3-3 describes how the PF s are used on the EZ-KIT Lite.
3.6.1 Using the Power Management Features PF14-PF12 allow you to program the core vo ltage of the DSP. The default core voltage is 1.5V. Table 3-4 gives the value of the core voltage corresponding to the state of these PFs. When lowering the core voltage of the D SP, the frequency of the DSP must be taken into consideration.
4 EZ-KIT LITE HARDW ARE REFERENCE 4.1 Overview This chapter describes the hardware design of the ADSP-21535 EZ-KIT Lite board. The following topics are covered: • System Architecture (Section 4.2 ) Describes the configuration of the DSP as well as a description of how all of the components on the bo ard interface with the DSP.
4.2 System Architecture The EZ-KIT Lite has been designed to demonstrate the capabilitie s of the ADSP- 21535 DSP. This section describes the DSP’s configuration on the EZ-KIT Lite board.
4.2.1 External Bus Interface The External Bus Interface Unit (EBIU) is connected to 4M x 32 bits of SDRAM (16 MB). This memory is connected to the synchronous memory select 0 (~SMS0) pin. Refer to section 3.4 for information about configuring the SDRAM.
4.2.3 Expansion Interface The expansion interface consis ts of the footprints for 3 connectors. The following table shows the interfaces each connector provid es. For the exact pin-out of these connectors refer to APPENDIX B: SCHEMATIC . Analog Devices does not populate these connectors or provide any ad ditional support for this interface.
4.3 Jumper and DIP Switch Settings This section describes the function of all the jumpers and DIP switches. The following figure shows the location of all the jumpers and DIP switches.
Stereo LINE_IN (DEFAULT) Mono MIC1 MIC JP1 LINE 2 1 6 5 MIC JP1 LINE 2 1 6 5 Figure 4-3: Audio Input Jumper Settings (JP1) 4.3.2 Audio Cod ec Disable Jumper (JP2) Placing a jumper between pins 1 and 2 of JP2 holds the AD1885 in reset, preventing it from driving si gnals to the serial port.
During reset, the function of these p ins is to setup the PLL. At this time, these signals are attached to the PLL setup switch (SW2) and determ ine the core and external clock speeds of the DSP. Appr oximately 120uS after reset has been de- asserted these pins are no longer a ttached to SW2, but function as PFs.
4.4 LEDs and Push Buttons This section describes the function of all the LEDs and push buttons. Figure 4-5 shows the location of all the LEDs and push buttons.
4.4.1 Programmable Flag LEDs (LED1, LED2, LED3, LED4) Four LEDs are connected to four of the DSP’s Progr ammable Flag (PF) pins, PF0-3. These LEDs are active HIGH and are lit by an output of “1” from the DSP. Refer to section 3.6 for m ore information about using of the PFs when programming the DSP.
4.4.6 Programmable Flag Push Bu ttons (SW4, SW5, SW6, SW7) Four push buttons are provided for general-purpose user input. SW4-7 connect to the DSP’s Programmable Flag (PF) pins, PF4-7. The push buttons are active high and when pressed send a high (1) to the DSP.
4.5 Connectors This section describes the function of th e connectors and gives information about mating connectors. The following figure s hows the locations of the connectors.
4.5.1 Expansion Interface (P1, P2, P3) Three board-to-board connector footprints provide the signals for most of the DSP peripheral interfaces. Analog Devices does not populate these connectors or provide any additional support for this interface. See section 4.
4.5.4 USB (P7) The USB connector is a standard Type B US B receptacle. This connector is used to debug the DSP, and is not connected to the DSP’s USB interface.
4.5.6 SPORT0 (P9) SPORT0 is connected to a 20- pin connector. The pinout fo r this connector can be found in APPENDIX B: SCHEMATIC . Contact AMP for pric ing and availability on these connectors.
