EZ-KIT Lite License Restrictions
For detailed information about programming the ADSP-21992 processor,
see “Related Documents” on page -xv.
EZ-KIT Lite License Restrictions
The license shipped with the EZ-KIT Lite imposes the following
restrictions.
• Program Memory (PM) space is limited to 8K words (1/4 of the
ADSP-21992 PM space).
• No connections to simulator or emulator sessions are allowed.
Restricted Software Breakpoints
Under some conditions, breakpoints cannot effectively be placed.
Generally, the emulator or EZ-KIT Lite development system restricts
breakpoint placement when certain conditions are met. These conditions
depend on things such as bus architecture, pipeline depth, and ordering.
Software Breakpoints Within Delayed Slots
Software breakpoints within a delayed slot, such as within two instructions of a delayed branch, are restricted.
In the following example, placing a breakpoint at 100 is acceptable. However, a breakpoint’s behavior at 101 or 102 is not defined and, therefore, is
restricted.
100 IF EQ JUMP 0x0000
/* .+0

Memory Map
The ADSP-21992 processor has 48K words of internal SRAM that can be
used for program storage or data storage. The configuration of internal
SRAM is detailed in the ADSP-2199x Mixed Signal DSP Controller Hardware Reference.
The ADSP-21992 EZ-KIT Lite board contains 512K x 8 bits of external
Flash memory. These flash memory ICs are connected to the boot memory select (BMS) pin or the memory select 0 (MS0) pin via a two-input
AND gate (U1). Jumper JP31 is placed on the MS0 line to disconnect the
MS0 pin if required. The flash memory can be accessed in either the boot
memory space or the external memory space.
If booting from the external flash memory IC, JP31 can be left open. In
this case, the external SRAM provided on the ADSP-21992 EZ-KIT Lite
board can be mapped to any of the external memory banks using one of
the jumpers (JP24 - JP27).
If not booting from the flash memory, but using it as external program or
data memory, JP31 must be closed. In this case, do not map the external
SRAM provided on the ADSP-21992 EZ-KIT Lite board to external
memory bank 0 (JP24 should be open in this case); instead, map it to any
of the other external memory banks using one of the jumpers (JP25 JP27).

Using the EZ-KIT Lite
Using Programmable Flag Pins
The ADSP-21992 DSP has eight asynchronous Programmable Flag (PF)
I/O pins (PF7–0) 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 (PF7–0) are used to set the multiplication factor,
which sets the core clock frequency. After the DSP is reset, the flags are configured as inputs. The direction of the flags is configured though the DIR register
and are set and read though the FLAGC/S register. For more information on
configuring the flag pins, see the ADSP-2199x Mixed Signal DSP Controller
Hardware Reference. Flags and their uses are described in Table 2-2.

System Architecture
System Architecture
This section describes the processor’s configuration on the EZ-KIT Lite
board.
The EZ-KIT Lite development system has been designed to provide access
to all the capabilities of the ADSP-21992 processor. For information
about configuring the boot mode, refer to “Boot Mode and Bypass Mode
Select Jumpers (JP9-JP12)” on page 3-16.
The processor core voltage is 2.5V, and the external interface operates at
3.3V. The analog input signal conditioning circuitry requires ±2.5V.
Power Supplies
Linear regulators are provided on the ADSP-21992 EZ-KIT Lite board for
the 2.5V and 3.3V required by the ADSP-21992 from a 5V source. The
linear regulators also provide the power for the digital peripheral circuitry
on the ADSP-21992 EZ-KIT Lite board.
Linear regulators are also provided for the ±2.5V from ±5V sources,
required by the analog input signal-conditioning circuitry. Appropriate
decoupling capacitors are provided on the ADSP-21992 EZ-KIT Lite
board for all power supply inputs (VDD, +AVDD, and -AVDD) to
reduce noise coupling from the external power supplies. However, for best
performance, well-regulated external power supplies and correct wiring are
recommended.
The ADSP-21992 EZ-KIT Lite board is laid out with separate analog and
digital ground planes, labeled AGND and DGND, respectively. JP1 is a
link that connects the analog and digital ground planes of the
ADSP-21992 EZ-KIT Lite board.

System Architecture
Reset Generation
The ADSP-21992 can be reset from a number of sources on the
ADSP-21992 EZ-KIT Lite board. The sources of reset for the
ADSP-21992 DSP are:
• POR (power-on reset output pin of the ADSP-21992)
• Reset button (S1)
• External power on reset IC (A7)
• USB Interface (software tools reset)
Choose the source of reset for the ADSP-21992 by configuring jumper
JP2. When JP2 is in the 2-3 position, the POR output pin of the
ADSP-21992 is tied to the reset pin of the ADSP-21992. When JP2 is in
the 1-2 position, the source of reset for the ADSP-21992 is the reset button (S1), the external power-on reset IC (ADM708), or a reset command
from VisualDSP++ through the USB interface. Position 1-2 (default) is
recommended when using the VisualDSP++ development tools.
Analog Input Interface
The ADSP-21992 EZ-KIT Lite board permits up to eight analog inputs to
be fed from the analog inputs connector (P4) to the eight ADC channels
of the ADSP-21992. All eight analog inputs at the analog inputs connector may range from -1V to +1V.
There is a separate interface circuit for each of the eight ADC channels of
the ADSP-21992. These analog interface circuits convert the nominal
±1V signals at the analog inputs connector P4 to signals centered on the
ADSP-21992 reference voltage level (either the internally derived 1.0V
level or the externally provided 1.024V level). The analog interface circuits, consisting of high-performance operational amplifiers and precision
resistors, effectively offset the analog inputs by the reference voltage level.
3-4
ADSP-21992 EZ-KIT Lite Evaluation System Manual
EZ-KIT Lite Hardware Reference
Two AD8044 quad operational amplifiers (A5 and A6) are used for the
analog interface and are configured as summing unity-gain stages. A5 is
used to interface the VIN0, VIN1, VIN2, and VIN3 analog inputs. A6 is used
to buffer the VIN4, VIN5, VIN6, and VIN7 inputs.
Precision 10 Kohm resistors for input and feedback ensure accurate gain
matching of all channels. In addition, 47 pF feedback capacitors provide
simple low-pass filtering with a very high cut-off frequency (339 kHz) on
all analog inputs.
The analog inputs are applied to the ADSP-21992 in a single-ended fashion, so that the inverting inputs to the sample-and-hold amplifiers of the
ADSP-21992 (ASHAN and BSHAN) are connected to a buffered version of the
reference voltage. A representation of the analog interface circuit for one
of the ADC channels is shown in Figure 3-2. As shown in the schematics
at the end of this document, each analog input stage also contains a small
RC filter at the operational amplifier output.

System Architecture
Reference Voltage Generation
The ADSP-21992 EZ-KIT Lite board contains an external voltage reference, the LM4140-1.0 (U3), which provides a precise 1.024V output. The
ADSP-21992 EZ-KIT Lite board can be configured to operate from the
internal (ADSP-21992 generated) or the external voltage reference. Two
jumpers control the selection of the internal or external voltage reference.
Jumper JP3 ties the SENSE pin of the ADSP-21992 to the AVDD or GND levels. Connecting SENSE to AVDD (JP3 in position 2-3) selects external voltage
reference operation. In this mode, the ADSP-21992 accepts an input voltage reference at the VREF pin.
To connect the external voltage reference to the ADSP-21992 on the evaluation board, close the JP4 jumper. This connects the external voltage
reference from the LM4140-1.0 to the VREF pin of the ADSP-21992. The
signal, which is buffered using an operational amplifier OP193 (A11),
level-shifts the applied analog input signals on the analog inputs connector, P4, (as well as being connected to the ASHAN and BSHAN inputs to the
sample-and-hold amplifiers).
To operate with the internally derived voltage reference of the
ADSP-21992, tie the JP3 jumper in position 1-2 to connect the SENSE pin
to AGND. Additionally, leave jumper JP4 open. The ADSP-21992 provides a 1V reference at the VREF pin that is buffered and applied to the
ASHAN and BSHAN inputs. The buffered VREF signal is also used in the
level-shifting circuitry.
See “Voltage Reference Selection Jumpers (JP3, JP4)” on page 3-14 for
more information.

Ground Plane Link (JP1)
is a link that connects the analog and digital ground planes of the
ADSP-21992 EZ-KIT Lite board.
JP1
! For correct operation, do not remove this link.
External/Internal DSP Reset Selection Jumper (JP2)
enables you to select the source of reset for the ADSP-21992. When
is in the 1-2 position, the ADSP-21992 can be reset from three external sources: pushbutton switch (S1), the external power-on reset IC
(ADM708), or the USB interface circuitry on the ADSP-21992 EZ-KIT
Lite board.

Jumper Settings
If JP2 is in the 2-3 position, the power-on reset (POR) of the
ADSP-21992 is directly connected to the reset pin of the ADSP-21992.
The 1-2 position (default) is the recommended configuration when using
the VisualDSP++ development tools.
Voltage Reference Selection Jumpers (JP3, JP4)
The configuration of two jumpers (JP3 and JP4) is required to control the
selection of the ADSP-21992 DSP’s internal voltage reference or the
external voltage reference provided on the ADSP-21992 EZ-KIT Lite
board. The appropriate settings for the jumpers to select internal or external voltage reference operation are:
• Internal reference:
P3
in position 1-2, and JP4 is open
• External reference:
P3
in position 2-3, and JP4 is closed
Refer to “Reference Voltage Generation” on page 3-6 for details on voltage voltage operation.
PWM Trip Jumper (JP5)
Connecting jumper JP5 in the 2-3 position ties the PWMTRIP pin of the
ADSP-21992 to +3.3V via a 4.7 Kohm resistor and enables the PWM outputs. In this case, the PWMTRIP pin of the ADSP-21992 can be defined by
external circuitry via the PWM connector (P10). Alternatively, connecting
jumper JP5 in the 1-2 position connects the PWMTRIP pin of the
ADSP-21992 to GND, thereby permanently disabling the PWM outputs. A
third alternative is to leave JP5 unconnected. Again, in this case, the pin of
the ADSP-21992 is connected to the PWM connector (P10) so that its value
can be defined by external circuitry.
3-14
ADSP-21992 EZ-KIT Lite Evaluation System Manual
EZ-KIT Lite Hardware Reference
PWM Switched Reluctance Mode Jumper (JP6)
Connecting JP36 in the 2-3 position ties the PWMSR pin of the
ADSP-21992 to +3.3V and disables the PWM switched reluctance mode.
Alternatively, connecting JP6 in the 1-2 position ties the PWMSR pin of the
ADSP-21992 to GND and enables PWM switched reluctance mode.
PWM Polarity Jumper (JP7)
Connecting JP7 in the 2-3 position ties the PWMPOL pin of the
ADSP-21992 to +3.3V and enables active HI PWM outputs. Alternatively,
connecting JP7 in the 1-2 position creates active LO PWM outputs from the
ADSP-21992. The appropriate setting for this jumper is determined by
the exact nature of the gate drive circuit of the target system. A third alternative is to leave JP5 unconnected. In this case, its state can be determined
by external hardware.
AUXPWM Trip Jumper (JP8)
Connecting jumper JP8 in the 2-3 position ties the AUXTRIP pin of the
ADSP-21992 to VDD and enables AUXPWM outputs. In this case, the AUXTRIP
pin of the ADSP-21992 can be defined by external circuitry, via the PWM
connector (P10). Alternatively, connecting jumper JP8 in the 1-2 position
connects the AUXTRIP pin of the ADSP-21992 to GND, thereby permanently
disabling AUXPWM outputs. A third alternative is to leave JP8 unconnected.
Again, in this case, the AUXTRIP pin of the ADSP-21992 is connected to
the PWM connector (P10) so that its value can be defined by external
circuitry.

Jumper Settings
Boot Mode and Bypass Mode Select Jumpers
(JP9-JP12)
The ADSP-21992 supports different boot modes, which are controlled by
the three dedicated hardware boot mode control pins (BMODE2, BMODE1,
and BMODE0). These modes can be selected by the configuration of the
three 2-pin jumpers (JP9-JP11). The default setting for these three 2-pin
jumpers is open, whereby no boot mode is selected.
The DSP provides a user-programmable (1x to 32x) multiplication of the
input clock, including fractional values, to support 128 external-to-internal (DSP core) clock ratios. The BYPASS pin, MSEL6-0, and DF bits in the
PLL configuration register, specify the PLL multiplication factor at reset.
When JP12 is closed, BYPASS mode is selected (default).
SPI EEPROM Enable Jumpers (JP13, JP14)
A socket is available on the ADSP-21992 EZ-KIT Lite board for an 8-pin
SPI Serial EEPROM, such as the Microchip 25LC640, which is used for
booting and/or data storage. JP13 and JP14 are used to enable the SPI
EEPROM. It is decoded at SPI slave select 1 via JP14. JP13 is used to
enable/disable the write protection pin of the SPI EEPROM.
DAC Enable Jumpers (JP15, JP16)
and JP14 enable the 8-channel, serial, 12-bit DAC on the
ADSP-21992 EZ-KIT Lite board. The DAC is decoded at SPI slave
select 2, via JP15. PF3 is used to update the DAC register via JP16.
JP13
SPORT/UART Circuitry Jumpers (JP17-JP21)
Jumper JP17 connects the transmit clock of the Serial port to the receive
clock of the Serial port.
3-16
ADSP-21992 EZ-KIT Lite Evaluation System Manual
EZ-KIT Lite Hardware Reference
Jumpers JP18-JP21 are used to configure the UART circuitry on the
ADSP-21992 EZ-KIT Lite board. JP18-JP20 enable the UART circuitry,
and JP21 enables the required loopback in the UART circuitry.
CAN Interface Jumpers (JP22-JP23)
A CAN transceiver (U2) is provided on the CAN interface. JP22 enables
(2-3 position) or disables (1-2 position) the sleep mode on the CAN transceiver. If no shunt is present, this mode can be defined by external
circuitry. Connectors P12 and P13 provide connections to the user’s CAN
bus and allow easy daisy-chaining of CAN devices. CAN bus termination
of 120 ohms is provided by closing jumper JP23.
External SRAM Enable Jumpers (JP24-JP27)
A 64K by 16-bit SRAM IC (U8) is provided on the External Memory
Interface (EMI) of the ADSP-21992 EZ-KIT Lite board. External memory space consists of four memory banks. Memory bank pins MS3 through
MS0 select banks 3-0, respectively. JP24–JP27 map the external SRAM to
MS0, MS1, MS2, or MS3.

Encoder Interface Jumpers (JP28-JP30)
The ADSP-21992 EZ-KIT Lite board allows you to apply differential
encoder signals to the board at the encoder interface connector (EIU), P6.
A differential line receiver IC (A8) is provided to convert the differential
encoder signals to single-ended signals for the EIU inputs of the
ADSP-21992. Three 2-pin jumpers (JP28–JP30) are provided to enable
this encoder interface circuitry. It is also possible to apply encoder signals
directly to the Encoder Interface of the ADSP-21992 at these jumpers,
when they are open (that is, when no shunt is installed).

External Flash Memory Enable Jumper (JP31)
Sockets are provided on the ADSP-21992 EZ-KIT Lite board to connect
the External Memory Interface to two 512K x 8-bit Flash memory ICs (U5
and U6). These Flash memory ICs are connected to the boot memory
select (BMS) pin, or to the memory select 0 pin (MS0) via a 2-input AND
gate. Jumper JP31 is placed on the MS0 line to disconnect the MS0 pin if
required.
