    Notes:
    1. The values include VDD, AVDD, and AVDD2 but do not include I/O supply power.
    2. Maximum—FP power is measured at VDD = 1.9 V with dynamic power management enabled while running an
    entirely cache-resident, looping, floating-point multiplication instruction.
    3. Maximum—INT power is measured at VDD = 1.9 V with dynamic power management enabled while running entirely
    cache-resident, looping, integer instructions.
    4. Power saving mode maximums are measured at VDD = 1.9 V while the device is in doze, nap, or sleep mode.
    5. Typical power is measured at VDD = AVDD = 1.8 V, GVDD_OVDD = 3.3 V where a nominal FP value, a nominal INT
    value, and a 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. Power consumption of PLL supply pins (AVDD and AVDD2) < 15 mW, guaranteed by design, but not tested.
    8. The typical maximum GVDD_OVDD value resulted from the MPC8241 operating at the fastest frequency
    combination of 66:133:266 (PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating
    ones and zeros to PCI memory and on 64-bit boundaries to local memory.
