4.3.2 SPDIF Selection Jumper (JP2)

JP2 is used select the SPDIF input to the CS8414 Digital Audio Receiver. When
the jumper is configured for an optical connection the TOSLINK optical input
connector (P4) should be used. When the jumper is configured for a coax
connection the RCA input connector (P5) should be used.

4.3.4 FLAG0 Enable (JP4)

In standard configuration, FLAG1 is connected to the AD1836 and used as a
select for the SPI port. This jumper should be removed to use the push button
switch or the signal on the expansion connector (P10). Once this jumper is
removed the SPI can no longer communicate with the AD1836.

4.3.5 FLAG1 Enable (JP5)

In standard configuration, FLAG1 is connected to the AD1852 and used as a
select for the SPI port. This jumper should be removed to use the push button
switch or the signal on the expansion connector (P10). Once this jumper is
removed the SPI can no longer communicate with the AD1852.

4.3.6 Sample Frequency Jumper (JP6)

JP6 is used to select the sample frequency for the AD1852. Table 4-3 shows the
valid modes that may be used.
