ADSP-21375 EZ-KIT Lite Evaluation System Manual
ELVIS Voltage Selection Jumper (JP3)
The ELVIS voltage selection jumper (
JP3
) is used to select the power
source for the EZ-KIT Lite. In a standard mode of operation, the board
receives its power from an external power supply. When
JP3
is installed,
the board is powered from an ELVIS station and no external power supply
is required. The jumper settings are shown in
[
The external power supply must be disconnected from the board
when
JP3
is installed to avoid potential damage to the EZ-KIT Lite
board and ELVIS unit.
ELVIS Programmable Flag Jumper (JP4)
The ELVIS programmable flag jumper (
JP4
) connects the ADSP-21375
processor’s
DAI4
pin to the ELVIS trigger pin. When
JP4
is installed,
DAI4
connects to the ELVIS
TRIG1_2
pin directly. Conversely, when
JP4
is
uninstalled, the
DAIP4
pin is disconnected and can be used for another
non-ELVIS operation. The jumper settings are shown in
