polarity is such that increasing voltage produces increasing fre-
quency. Logic “0” causes CP_OUT to source current when f VCO /M
> f REF /R. This state is used when increasing tune voltage causes
the VCO frequency to decrease.

Must be 0 for normal operation.
Logic “1” activates turbocharge mode, which provides rapid fre-
quency acquisition in the PLL.
Logic “1” selects M1/R1 divide ratios. Logic “0” selects M2/R2.
Logic “1” bypasses the VCO inputs for external VCO operation.
Logic “1” selects VCO_H. Logic “0” selects VCO_L.
Logic “1” selects divide-by-2 on LOOUT port. Logic “0” bypasses
divider.
Logic “1” disables LOOUT. Logic “0” enables LOOUT.
Active in FM mode. Logic “0” selects quadrature demodulator for
FM mode. Logic “1” selects downconversion to I port.
Logic “0” selects FM input port. Logic “1” selects CDMA input.
Logic “0” enables standby mode, which shuts down the VGA and

Logic “0” enables register-based shutdown. This mode shuts down
everything except the M and R latches and the serial bus.
