3.3V LVTTL inputs for CPU frequency selection
.
A precision resistor is attached to this pin which is connected to the
internal current reference
.
3.3V LVTTL input for Power_Down# (active LOW)
.
3.3V LVTTL input for PCI_STOP# (active LOW)
.
3.3V LVTTL input for CPU_STOP# (active LOW)
.
3.3V LVTTL input is a level-sensitive strobe used to determine when S[2:1]
inputs are valid and OK to be sampled (Active LOW)
. Once VTT_PWRGD#
is sampled LOW, the status of this input will be ignored.
