N Divider Programming b(7:0)
The decimal representation of
M and N Divier in Byte 11 and
12 will configure the VCO
frequency. Default at power
up = latch-in or Byte 0 Rom
table. VCO Frequency =
14.318 x [NDiv(9:0)+8] /
[MDiv(5:0)+2]
Reserved
Byte Count Programming b(7:0)
Writing to this register will
congiure how many bytes will
be read back, default is 9
bytes.
