Bits Name Access Function
18:16 OD Read/write Output divider:
000 = divide by 10
001 = divide by 2
010 = divide by 8
011 = divide by 4
100 = divide by 5
101 = divide by 7
110 = divide by 9
111 = divide by 6.
15:9 RDW Read/write Reference divider word. Defines the binary value of
the R[6:0] pins of the clock generator.
8:0 VDW Read/write VCO divider word. Defines the binary value of the
V[8:0] pins of the clock generator.
