-LM700x is a frequency synthesizer IC.
-The LM700x is programmed through a 24-bit write-only shift register.
-The first 14 bits are frequency data.
-The next 2 bits are LSI test bits, and should always be zero.
-The next 4 bits are band data and time base data.
-They can be programmed to force a given reference frequency, or they can be
-set to zero and the next 3 bits can be used to set the reference frequency.
-The final bit selects the divider selection, which is 1 for FM and 0 for AM.
