DESCRIPTION
1-4
N1[0]..N1[3]
Sets N1 modulus according to this table. These bits are set to implement
a divide-by-four on power-up.

RESERVED
Must be set to zero.
6
JAMPLL
Tristates phase detector outputs, resets phase detector logic, and resets
R, A, M, and N2 counters.
7
DACRST
Set to zero for normal operations. When set to one, the CLK+ output is
kept high and the CLK- output is kept low. (All other device functions are
unaffected.) When returned to zero, the CLK+ and CLK- outputs will
resume toggling on a rising edge of the LD output (+/
1 CLK period).
To initiate a RAMDAC reset sequence, simply write a one to this register
bit followed by a zero.
8
SELXTAL
When set to logic 1, passes the reference frequency to the post-scaler.
9
ALTLOOP
Controls substitution of N1 and N2 dividers into feedback loop of PLL.
When this bit is a logic 1, the N1 and N2 dividers are used.
10
SCEN
VRAM shift clock enable bit. When logic 1, the BLANK pin can be used
to disable the LD/N2 output.
11
EXTFBKEN
External PLL feedback select. When logic 1, the EXTFBK pin is used for
the phase-frequency detector feedback input.
12
PDRSTEN
Phase detector reset enable control bit. When this bit is set, a high level
on the BLANK input will disable PLL locking. See "Internal Feedback
Operation" section for more details on the operation of this function.
