ADSP-BF592 EZ-KIT Lite Hardware Reference
SPORT0 Enable Switch (SW1)
The SPORT0 enable switch (
SW1
) disconnects the codec from the
SPORT0 interface of the processor and allows the SPORT0 signals to be
used on the expansion interface. Refer to
“Audio Interface” on page 1-13
for more information.
UART Setup Switch (SW2)
The UART setup switch (
SW2
) configures UART signals between the DCE
connector (
J1
) and processor. Table 2-3 shows operation of the switches
turned on. See “DCE UART Connector (J1)” on page 2-19 for more
information.
Battery Switch (SW3)
The battery switch (
SW3
) connects and disconnects the lithium ion battery
from the EZ-KIT Lite power. When the switch is
ON
, the board can run
from the battery. Jumper
JP7
must be removed when
SW3
is
OFF
. By
default,
SW3
is
OFF
.
