Signal Function
Control bits for VCO ALC loop;
ROW14<3:2> = 01 for normal operation
Controls slew rate in sub-integer N divider

Read only bits to indicate synthesizer lock:
ROW15<7:6> =
01 indicates that the VCO control voltage is within the lock window and the synthe-
sizer is locked.
11 indicates the VCO control voltage above lock window
00 below lock window
10 is a disallowed state indicating an error
