Program to zero.
SDO Output Control Register.
The mux_output table is as follows:
Notes:
Program to zero.
RF PLL Update Rate (RF1 VCO only).
0 = 200 kHz update rate (Receive GSM modes).
1 = 100 kHz update rate (Receive DCS and PCS modes).
Note: This bit is set to 1 when register 20h D[17:16] = 01
Input Clock Frequency.
0 = No divider. XIN = 13 MHz.
1 = Divide XIN by 2. XIN = 26 MHz.
Program to zero.
Program to one.
1. SDO is high-impedance when PDN = 0.
2. SDO is Serial Data Output when in register read mode.
0000 Connected to the Output Shift Register (default).
0001 Force the Output to Low.
