Program to zero.
N Divider for RF PLL (RF2 VCO).
Used for transmit mode.
0
Program to zero.
N Divider for RF PLL (RF1 VCO).
Used for receive mode.

0
Program to zero.
Powerdown IF PLL.
0 = IF synthesizer powered down.
1 = IF synthesizer powered up when the PDN pin is high.
Notes:
Powerdown RF PLL.
0 = RF synthesizer powered down.
1 = RF synthesizer powered up when the PDN pin is high.
Notes:
1. The IF PLL is only used in transmit mode. Powerdown for receive mode.
2. This bit is set to 0 when register 20h is written (receive mode).
3. This bit is set to 1 when register 23h is written (transmit mode).
1. This bit is set to 1 when register 20h is written (receive mode).
2. This bit is set to 1 when register 23h is written (transmit mode).
