0-3
0-2
R[0]..R[3]
R[4]..R[6]
Reference divider modulus control bits
Modulus = value + 1
2
0-3
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.

0-3
0-1
M[0]..M[3]
M[4]..M[5]
M counter control bits
Modulus = value + 1

3
DBLFREQ
Doubles modulus of dual-modulus prescaler (from 6/7 to 12/14).
5
0-2
N1[0]..N1[2]
Sets N1 modulus according to this table. These bits are set to imple-
ment a divide-by-four on power-up.
6
7
0-3
0-3
N2[0]..N2[3]
N2[4]..N2[7]
Sets the modulus of the N2 divider. Modulus = value + 1
The input of the N2 divider is the output of the N1 divider in all clock
modes except AUXEN.
