JP14
JP14 connects the Shutdown input of the FLATLINK™
transmitter at U32 to reset, or GND
1 + 2
The X_nReset_PWRON signal of the phyCORE-OMAP44xx
shuts down the FLATLINK™ transmitter to avoid bad
display signals during reset
2 + 3
The Shutdown input of the FLATLINK™ transmitter is
connected to GND in order to disable the device (e.g. if a
custom display interface is connected to extension
connector X5)
JP15, JP16
JP15 and JP16 select the source for audio connector X14.
X14 can serve as either headphone output connector, or as
stereo line out connector. JP15 selects the source of the
right channel, while JP16 connects the left channel of the
desired source to connector X14.
1+2
Audio jack X14 serves as headphone output connector
2+3
The stereo line out signals are available at audio jack X14
J3
In combination with jumpers J4 and J8, and resistors R25
and R26 jumper J3 allows to configure the various
operating modes of the RS-232 transceiver at U2.
J3 connects the Force-On input of the RS-232 transceiver
to pad 2 of jumper J8 for further configuration.
