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
is directly connected to the ELVIS
TRIG1_2 pin. Conversely, when JP4 is
uninstalled, the
DAIP4 pin is disconnected and can be used for other
non-ELVIS functionality. The jumper settings are shown in Table 2-13.

Expansion Interface Connectors (J1–J3)
Three board-to-board connectors (J1–3) provide signals for most of the
processor’s peripheral interfaces. The connectors are located at the bottom
of the board. For more information about the expansion interface, see
“Expansion Interface” on page 2-7. For the
J1–3 connectors’ availability
