R = 16 with reference divider = 512 R = 20 with reference divider = 640 R = 32 with reference divider =1024

Control byte 1 CP can be set to either 0 (low current) or 1 (high current). Charge pump settings: CP = 1, for fast tuning CP = 0, for moderate speed tuning with slightly better residual oscilator FM. Unnecessary charge pump action will result in very low tuning voltage (VT=0V) which may drive the oscillator to extreme conditions.
