Description
Synthesized frequency divisor (8 LSBs of a 13-bit word).
Default yields 300 kHz from 18 MHz; Minimum = 3,
Maximum = 8191.
Enable fast acquire.
Invert charge pump (0 = source current to increase VCO
frequency).
Charge pump current in normal operation.

PUMP
= (CKI + 1) × 0.625 mA.
Manual control of CLK charge pump (0 = Off, 1 = Up, 2 = Down,
and 3 = Normal).
CK fast acquire time unit (6 LSBs of a 14-bit word).
CK fast acquire time unit (8 LSBs of a 14-bit word).
