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 sup-
ply is required. The jumper settings are shown in Table 2-12.
[
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-21369
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,
DAIP4 is disconnected and can be used for another non-ELVIS
operation. The jumper settings are shown in Table 2-13.
