pull-up.
If MODE = 1 (default), then this pin is a PCI5 clock
output. If MODE = 0 , then this pin is PCI_STOP #
and used in power management mode for
synchronously stopping the all PCI clocks.

pull-up.
If MODE =1 (default), then this pin is a REF1
buffered output of the crystal. If MODE = 0 , then this
pin is CPU_STOP# input used in power
management mode for synchronously stopping the
all CPU clocks.

I/O
Internal 250k
pull-up.
Latched input for FS0 at initial power up for H/W
selecting the output frequency of CPU, SDRAM and
PCI clocks. 48MHz output for USB during normal
operation.
