Figure 12. Mott Canyon 4 Interposer Card 
 
A.1.1 
Jumper Settings 
The Mott Canyon 4 Interposer card can select either Primary or Secondary Intel® HD 
Audio functionality for MDC0 and MDC1 connectors with two jumper options, J16 and 
J25.  
In Intel® HD Audio mode, MDC0 is designed to house the primary codec (usually 
audio but could be modem if there is no audio) and if necessary, MDC1 is designed to 
house the modem codec. MDC2 supports an Intel® HD Audio modem-only codec. 
The Intel® SCH supports up to two SDATA_IN channels (0, 1). Two jumpers, J27 and 
J28 are used to select the appropriate SDATA_IN channels for each of the MDCs. Be 
aware that SDATA_IN channels 1 and 2 can be also overridden through jumpers on 
the evaluation platform. If either SDATA_IN1 or SDATA_IN2 are not shunted properly 
on the evaluation platform, these lines are not available to the Mott Canyon 4 
Interposer card. Proper operation of the Intel® HD Audio interface requires that only 
one SDATA_IN line is routed to one codec at a time.
