SP8852E - 27GHz Parallel Load Professional Synthesiser
These are the inputs to the 16-bit data bus.
When pin 38 is high the data goes to the buffers for the A counter, M counter and phase detector gain.
When pin 38 is low the data goes to the buffers for the reference counter and the phase detector state (see Table 4).
