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 the PLL
bypass mode.
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 the dual PLL bypass mode.
