Intel NetStructure® MPCBL0010 Single Board Computer
October 2006 Technical Product Specification
Order Number: 304120 111
Addressing—MPCBL0010 SBC
ReqClk3A: A copy of bit DRVCLK3A of register TelClock3: when this bit is set, the
application that configures the TelClock module requests to drive CLK3A in the
backplane.
ReqClk3B: A copy of bit DRVCLK3B of register TelClock3. When this bit is set, the
application that configures the TelClock module requests to drive CLK3A in the
backplane.
On a power fail (i.e. that causes a reset), the content of register SBC Status (register
01h) is captured here. See the SBC Status register for the detailed bit definition.
FWH0: 1 = connect FWH0 to IPMC; 0 = connect FWH0 to ICH
FWH1: 1 = connect FWH1 to IPMC; 0 = connect FWH1 to ICH
FWHID: Value of ID[0] of FWH0 matches this bit; FWH1 has the inverted value
If the main processor needs to change the ID of the FWH, it has to ask the IPMC to do
it.
Note: The default configuration connects FWH0 and FWH1 to the ICH.
SW: Direct reading of the reset switch: 1 = switch pressed; 0 = switch released
