PCI clock stop control pin, This pin is low active. Internal 120kΩ
pull up, Selected by Register 1 bit 6= 0 and Register 9 bit 6 = 1,
see Page 10 Table 2.
Latched input for FS1 at initial power up for H/W selecting the
output frequency clocks. This is internal 120KΩ pull down.
Power on trapping for different current reference. The reference
current is referred for Pin 25 (IREF), see page 5 Table 1. This
pin is latched during VTT_PWRGD#. This pin is internal pull up
120K.
14.318MHz output.
Latched input for FS0 at initial power up for H/W selecting the
output frequency clocks. This is internal 120KΩ pull up.
14.318MHz output.
If SELP4_K7=1 than Power good input signal comes from
ACPI with low active. This 3.3V input is level sensitive strobe
used to determine FS [3:0] and MULTSEL input are valid and
is ready to sample. This pin is low active.
48MHz clock output.
Latched input for FS3 at initial power up for H/W selecting the
output frequency clocks. This is internal 120KΩ pull up.
24MHz clock output
Latched input for FS2 at initial power up for H/W selecting the
output frequency clocks. This is internal 120KΩ pull down.
