MPCBL0010 SBC—Addressing
Intel NetStructure® MPCBL0010 Single Board Computer
Technical Product Specification October 2006
108 Order Number: 304120
Even though authorization is given by the IPMC to drive the clocks to the AdvancedMC
module, no actual clocks are driven if the module is not present, unpowered, or
illpowered. These bits can be set prior to turning on the AdvancedMC module’s power.
A readback returns the state of the bit, but does not reflect the actual clock. In the case
of bad power (12VFault=1 for example), the clock is not driven even if the
authorization bit is set. On an AdvancedMC extraction, these bits are automatically
cleared.
MRLSw: Mechanical retention latch status for MCH (IPMC must write this bit)
Fault#: Fault indication for MCH (IPMC must write this bit)
AttSw: Attention switch for MCH (IPMC must write this bit)
Present#: AdvancedMC presence for MCH (IPMC must write 0 for presence)
En3V: Enables 3.3V power: bit is locked in "0" state if no AdvancedMC module is
present
En12V: Enables 12V power: bit is locked in "0" state if no AdvancedMC module is
present
EnIPMCB: Enables I2C link on AdvancedMC module: bit is locked in "0" state if no
AdvancedMC module is present
EnAMC: Enables AdvancedMC module: bit is locked in "0" state if no AdvancedMC
module is present
Present: Indicates that an AdvancedMC module is present
3VFault: Fault on 3.3V voltage from an overcurrent
3V0k: Valid 3.3V voltage
12VFault: Fault on 1 2V volta ge
12V0k: Valid 12V voltage
ClkAEn: Authorizes the telecom clock circuit to drive synchronization clock CLKA
ClkCEn: Authorizes the 100 MHz PCI-Express clock driver for this AdvancedMC module.
