Mott Canyon 4 Jumper Settings

The Mott Canyon 4 Interposer has the ability to select either Primary or Secondary
Intel HD Audio functionality for MDC0 and MDC1 connectors with two jumper options,
J16 and J25. See the Table 24 below for details. MDC2 supports an Intel® High
Definition Audio modem-only codec.
The ICH9M supports up to 4 SDATA_IN channels (0, 1, 2 & 3). MC4 supports three
channels (0, 1 &2) of codecs. Mapping of four ICH9M channels on MC4 card can be
done using strapping resistors on the development board. Three jumpers: J27, J28,
and J29 are used to select the appropriate SDATA_IN channel for MDC. The default
and optional mapping of SDATA_IN signals are shown in Table 24. Please be aware
that SDATA_IN channels 1 and 2 can also be overridden via jumpers on the evaluation
platform. If either SDATA_IN1 or SDATA_IN2 are not shunted properly on the
evaluation platform, these lines will not be available to the Mott Canyon 4 Interposer
Card. Proper operation of the Intel HD Audio interface requires that only one
SDATA_IN line to be routed to one codec at a time.
