Notes:
1. Limited by maximum PCI input frequency (66 MHz).
2. Limited by maximum system memory interface operating frequency (100 MHz @ 350 MHz CPU).
3. Limited by minimum memory VCO frequency (132 MHz).
4. Limited due to maximum memory VCO frequency (372 MHz).
5. Limited by maximum CPU operating frequency.
6. Limited by minimum CPU VCO frequency (360 MHz).
7. Limited by maximum CPU VCO frequency (800 MHz).
8. In clock off mode, no clocking occurs inside the MPC8245 regardless of the PCI_SYNC_IN input.
9. Range values are shown rounded down to the nearest whole number (decimal place accuracy removed) for clarity.
10. PLL_CFG[0:4] settings not listed are reserved.
11. Multiplier ratios for this PLL_CFG[0:4] setting are different from the MPC8240 and are not backwards-compatible.
12. PCI_SYNC_IN range for this PLL_CFG[0:4] setting is different from the MPC8240 and may not be fully
backwards-compatible.
13. Bits 7–4 of register offset <0xE2> contain the PLL_CFG[0:4] setting value.
14. In PLL bypass mode, the PCI_SYNC_IN input signal clocks the internal processor directly, the peripheral logic PLL
is disabled, and the bus mode is set for 1:1 (PCI:Mem) mode operation. This mode is intended for hardware
modeling support. The AC timing specifications given in this document do not apply in PLL bypass mode.
15. In dual PLL bypass mode, the PCI_SYNC_IN input signal clocks the internal peripheral logic directly, the peripheral
logic PLL is disabled, and the bus mode is set for 1:1 (PCI_SYNC_IN:Mem) mode operation. In this mode, the
OSC_IN input signal clocks the internal processor directly in 1:1 (OSC_IN:CPU) mode operation, and the
processor PLL is disabled. The PCI_SYNC_IN and OSC_IN input clocks must be externally synchronized. This
mode is intended for hardware modeling support. The AC timing specifications given in this document do not apply
in dual PLL bypass mode.
16. Limited by maximum system memory interface operating frequency (133 MHz @ 333 MHz CPU).
17. Limited by minimum CPU operating frequency (100 MHz).
18. Limited by minimum memory bus frequency (50 MHz).
19. PCI_SYNC_IN range for this PLL_CFG[0:4] setting does not exist on the MPC8240 and may not be fully
backwards-compatible.
20. No longer supported.
