ADSP-21992 EZ-KIT Lite Evaluation System Manual
4-34
4.2.11 Programmable Flag Pins Interface
All programmable flag pins are available on connector P8. Refer to
in section
for
the configuration of P8.
4.2.12 PWM Generation Unit Interface
All six PWM output signals, AH–CL, are available at the PWM output connector, P10. The
PWMSYNC output is also available at the connector, P10. A
PWMTRIP
input can be applied at
connector P10. Refer to
in section
for the configuration of P10.
Three jumpers are provided for the configuration of the PWM Generation Unit of the ADSP-
21992. JP5 is used to enable/disable the
PWMTRIP
input. JP6 is used to enable/disable PWM
switched reluctance mode. JP7 configures the polarity of the PWM output signals.
4.2.13 Auxiliary PWM Unit Interface
Both AUXPWM outputs signals, AUX0 and AUX1, are available on connector P10. An
AUXTRIP
input can be applied at connector P10. A jumper, JP8, is provided to enable/disable
the
AUXTRIP
input signal. Refer to
in section
for the configuration of P10.
4.2.14 General-Purpose Timer Signals
The three general-purpose timer input/output signals (TMR0, TMR1, and TMR2) are available at
connector P10. Refer to
in section
for the configuration of P10.
4.2.15 Encoder Interface Unit Circuitry
The ADSP-21992 EZ-KIT Lite board allows you to apply differential encoder signals to the
board at the encoder interface connector, P6. A differential line receiver, A8, is provided to
convert the differential encoder signals to single-ended signals for the EIU inputs of the ADSP-
21992. Three jumpers (JP28, JP29, 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.
4.2.16 JTAG Emulation Port
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
for more information about the JTAG
connector. To learn more about available emulators, contact Analog Devices. See section
for
information about contacting Analog Devices.
