*OS is the OFFSET default setting. OS is the integer value of the five MSBs of RANGE register.

DS1085

These ranges include values outside the oscillator range of 66MHz to 133MHz. When using these ranges,

values of DAC must be chosen to keep the oscillator within range. Correct operation of the device is not

guaranteed outside the range 66MHz to 133MHz.

MUX WORD (Address 02h)

The MUX word controls several functions. Its bits are organized as follows:
