BIT(S)
BIT REF.
DESCRIPTION
33-38
M[0]..M[5]
M counter control bits
Modulus = value +1
39
FBKPOL
External feedback polarity control bit. The PLL will lock to the falling
edge of EXTFBK when FBKPOL=1 and to the rising edge of EXTFBK
when FBKPOL=0.
40
DBLFREQ
Doubles modulus of dual-modulus prescaler (from 6/7 to 12/14).
41-44
A[0]..A[3]
Controls A counter. When set to zero, modulus=7. Otherwise,
modulus=7 for “value” underflows of the prescaler, and modulus=6
thereafter until M counter underflows.
45
RESERVED
Set to zero.
46
LOADEN~
Load clock divider enable (active low). When set to logic 1, the LOAD
and LD/N2 outputs will cease toggling.
47
SKEW-
Differential output duty factor adjust.
48
SKEW+
49-55
R[0]..R[6]
Reference divider modulus control bits
Modulus = value + 1
56
REFPOL
PLL locks to the rising edge of XTAL1 input when REFPOL=1 and to
the falling edge of XTAL1 when REFPOL=0.
SKEW+
SKEW-
0
Default
