Description
Reserved. Default = 0
AGCPDM. Default=00. AGC PDM control range
00: PDM 3.3V : Use when VDDM = 3.3V
01: PDM 2.4V : Use when VDDM = 2.4V
10: PDM 2.7V : Use when VDDM = 2.7V
11: Reserved : not allowed.
Reserved bit for changes to PDM voltage according to the
MODEM power voltage BIT.
Reserved. Default = 0
AGCPON. Default=1. RX AGC power control
1: Power on : allows AGC
0: Power down mode : not allow AGC .
RVCOLVL. Default=0. RXVCO output level control
1: Outputs RXVCO_OUT normally.
0: Reduces RXVCO_OUT by -2dB.
Bit to eliminate the harmonic component that can be caused by
RX VCO.
RVCO. Default = 11.
00: All block Power down, excluding TCXO/N.
01: Mode that forces external VCO in the VCO Tank.
10: Mode that forces external VCO in the VCO Tank.
11: Normal VCO Mode.
VCO operating mode defining bit.
