SW PCI_STP# Function
0 = SW PCI_STP assert, 1 = SW PCI_STP deassert
When this bit is set to 0, all STOPPABLE PCI, PCIF and SRC outputs will
be stopped in a synchronous manner with no short pulses.
When this bit is set to 1, all STOPPED PCI, PCIF and SRC outputs will
resume in a synchronous manner with no short pulses.
If Prog_CPU_EN is set, the values programmed in CPU_DAF_N[8:0] and
CPU_DAF_M[6:0] will be used to determine the CPU output frequency. The
setting of the FS_Override bit determines the frequency ratio for CPU and
other output clocks. When it is cleared, the same frequency ratio stated in
the Latched FS[C:A] register will be used. When it is set, the frequency ratio
stated in the FSEL[2:0] register will be used
See Byte 14 for description
If Prog_CPU_EN is set, the values programmed are in CPU_FSEL_N[8:0]
and CPU_FSEL_M[6:0] will be used to determine the CPU output
frequency. The setting of the FS_Override bit determines the frequency
ratio for CPU and other output clocks. When it is cleared, the same
frequency ratio stated in the Latched FS[C:A] register will be used. When it
is set, the frequency ratio stated in the FSEL[2:0] register will be used
If Prog_SRC_EN is set, the values programmed in SRC_DAF_N[7:0] will
be used to determine the SRC output frequency.
Enable Smooth Switching, 0 = Disabled, 1= Enabled
Smooth switch select, 0 = CPU_PLL, 1 = SRC_PLL
