0 selects LOL input port; 1 selects LOH port.
Works in conjunction with RCP_TURBO2 (CONFIG register) to set the turbo-
charge pump mode. (See Table 7)
1 keeps IF turbo-mode current active even when frequency acquisition is
achieved. This mode is used when high operating IF charge-pump current is
needed.
Sets operating mode according to the following:
00 = FM mode
01 = Cellular digital mode, RFL is selected
10 = Lower half-band PCS mode, RFH1 is selected
11 = Upper half-band PCS, RFH0 is selected
1 selects IFINH and IFOUTH; 0 selects IFINL and IFOUTL. For FM mode
(MODE = 00), set IF_SEL to 0.
1 selects high-band IF VCO; 0 selects low-band IF VCO.
3-Bit IF gain Control. Alters IF gain by approximately 2dB per LSB (0 to 14dB).
Provides a means for adjusting balance between RF and IF gain for optimized
linearity.
When this bit is 1, the upper sideband is selected (LO below RF). When this bit
is 0, the lower sideband is selected (LO above RF).
0 turns IFLO buffer off; 1 turns IFLO buffer on.
0 selects direct VCO modulation. (IF VCO is externally modulated and the I/Q
modulator is bypassed); 1 selects quadrature modulation.
0 shuts down everything except registers and serial interface.
0 shuts down modulator and upconverter, leaving PLLs locked and registers
active. This is the programmable equivalent to the TXGATE pin.
0 shuts down everything except serial interface, and also retains all register
settings.
