ADSP-21262 EZ-KIT Lite Evaluation System Manual
the device is a slave, the DSP must generate the frame sync and clock sig-
nals. By default, position 3 is “
ON
”, and the AD1835A generates the
control signals.
Position 4 of
SW7
disconnects the AD1835A’s
ADC_DATA
pin from the DAI
interface. This is useful when the DAI interface is to connect to another
device.
SPDIF Signal Enable Switch (SW8)
The SPDIF signal enable switch (
SW8
) disconnects always driving signal of
the CS8416 SPDIF receiver serial interface.
Table 3-3
shows which DSP signal is no longer being driven when the
corresponding switch position is placed in the “
OFF
” position.
Push Button Enable Switch (SW9)
The push button enable switch (
SW9
) disconnects the push buttons from
the corresponding DSP pins. This allows the signals to be used for another
purpose.
Table 3-4
shows the signal and
SW9
connections. By default, all
of the position of the
SW9
switch are “
ON
”, allowing the push buttons to
function as designed.
