more information on jumper setting please see section 4.5 of this manual.
4.7 LEDs
The ADSP2192-12 EZ-KIT Lite has a total of six LEDs for power indication, reset indication, and
GPIO flag indication. The following is a more detailed description of the functionality of each
respective LED.
•
LED1 is a dual light emitting diode package. The red light emitting diode indicates that
pushbutton reset is depressed and the \RESET is asserted. The green light emitting diode
indicates that the PCI bus is powering the board and SW4 is set to the correct position signifying
PCI operation.
•
LED2 is a green light emitting diode, which indicates that the board is being powered by a user-
provided external power supply and SW4 is set to the left position signifying, Stand-alone or
USB operation.
•
LED3 is a green light emitting diode, which indicates that the EZ-KIT Lite has power and
ADSP2192-12 DSP core is being powered by 2.5V.
•
LED4 is a dual light emitting diode package. Both LEDs are yellow and indicate status of the
GPIO1 and GPIO0 lines of the ADSP2192-12 processor.
4.8 Serial EEPROM
The ADSP2192-12 EZ-Kit Lite provides socketed pins (U2) for an optional Serial EEPROM. The
EEPROM is not required for operation of the board. It is only necessary if you want to modify the
internal ROM code of the ADSP2192-12. If a customer wishes to install an EEPROM, then he or she
can use one of the following devices or one that is electrically similar:
