value where there is a continuous flush of cache lines with alternating ones and zeros on 64-bit boundaries to local memory

are averaged.

6.

Power saving mode data measured with only two PCI_CLKs and two SDRAM_CLKs enabled.

7.

The typical minimum I/O power values was the result of the MPC8245 performing cache resident integer operations at the

slowest frequency combination of 33:66:200 (PCI:Mem:CPU) MHz.

8.

66:133:399 (PCI:Mem:CPU) MHz for the 400-MHz part, 66:133:466 (PCI:Mem:CPU) MHz for the 466-MHz part, and

performing continuous flushes of cache lines with alternating ones and zeros to PCI memory.

9.

66:133:399 (PCI:Mem:CPU) MHz for the 400-MHz part, 66:133:466 (PCI:Mem:CPU) MHz for the 466-MHz part, and

performing continuous flushes of cache lines with alternating ones and zeros on 64-bit boundaries to local memory.
