LPC Interface Bridge Registers (D31:F0)

Note: Writes to this register will initiate an Intel SpeedStep technology transition, which involves a
SS_CNT— Intel
Default Value
Lockable:
Power Well:
temporary transition to a C3-like state in which the STPCLK# signal will go active. An Intel
SpeedStep technology transition always occur on writes to the SS_CNT register, even if the value
written to SS_STATE is the same as the previous value (after this “transition” the system would
still be in the same Intel SpeedStep technology state). If the SS_EN bit is 0, then writes to this
register will have no effect and reads will return 0.
I/O Address:
7:1
Bit
0
Reserved
Intel SpeedStep technology State (SS_STATE) — R/W (Special). When this bit is read, it will
return the current Intel SpeedStep technology state. Writes to this register will cause a change to the
Intel SpeedStep technology state indicated by the value written to this bit.
0 = High power state.
1 = Low power state.(default)
