Power Management
Note 1. On power up, the FID[3:0] pins are set to a clock multiplier value of 6x for the NX 1750@14W and NX 1500@6W
Note 2. Value programmed into the FidVidCtl MSR (MSR C001_0041h).
Note 3. The maximum FID that may be selected by software is reported in the FidVidStatus MSR (MSR C001_0042h).
Note 4. BIOS initializes the CLK_Ctl MSR (MSR C001_001Bh) during the POST routine to the desired value. The CPU ID
Note 5. Value driven on SDATA[36:32]# pins during the FID_Change special bus cycle. The SDATA bus is active Low, so
*The AMD Geode NX 1750@14W processor operates at 1.4 GHz, the NX 1500@6W processor operates at 1.0 GHz, and the NX 1250@6W processor operates at
667 MHz. Model numbers reflect performance as described here: http://www.amd.com/connectivitysolutions/geodenxbenchmark.

cessor to the desired frequency.
and implemented features such as PowerNow! and S2K Bus Disconnect have implications to the appropriate value
for this register. Refer to the AMD Geode™ NX Processors BIOS Considerations Application Note (publication ID
32483) and the BIOS Requirements for BIOS Requirements for AMD PowerNow™ Technology Application Note
(publication ID 25264) for more details on the CLK_Ctl register.
the SDATA[36:32]# values listed are what would be observed on the circuit board with a digital storage scope.
