0x=PLL is enabled by RXEN|TXEN|TXST
10=PLL is always disabled
11=PLL is always enabled
Use Alternate mode of PA ramping and data gating. If enabled, the RU_DLY[4:0]

If this bit is set high then the first 16 MCK data bits loaded after MD_DLY1
If programmed high, a nominal delay of 3nsec is added to the MCK input.

Enables GPRS mode 2. In this GPRS mode, the DAC1 will ramp down before
0=GPRS mode 2 disabled
1=GPRS mode 2 enabled
Enables GPRS mode 1. In this GPRS mode, the DAC1 will ramp to the new power
0=GPRS mode 1 is disabled
1=GPRS mode 1 is enabled
Digital RX Interface Mode
000=I and Q data are multiplexed on the DRI pin with 12-bit accuracy, 13MHz
001=I and Q data are presented on the DRI and DRQ pins with 16-bit accuracy,
010=I and Q data are presented on the DRI pin with 16-bit accuracy, 8.667MHz
011=I and Q data are presented on the DRI pin with 16-bit accuracy, 13MHz
100=I and Q data are presented on the DRI pin with 16-bit accuracy, 26MHz
101=I and Q data are presented on the DRI pin with 12-bit accuracy, 26MHz
110=I and Q data are presented on the DRI and DRQ pins with 16-bit accuracy,
111=same as 000
RX Interface Mode
0=analog mode
1=digital mode
SSI Word Rate
0=SSI word rate is equal to the GSM symbol rate
1=SSI word rate is equal to twice the GSM symbol rate
TRD Receive Mode Settings
When RXEN is high, {GPO3, GPO2, GPO1 pins}=TRDC_RX(2:0) for a period
When RXEN is low, {GPO3, GPO2, GPO1 pins}={GPO3, GPO2, GPO1}.
mode voltage of mid-supply ±200mV. Use 1 for interface to other front-ends
with common mode voltage outside of this range.
and RD_DLY[4:0] registers are used to delay the DAC1 ramp up and ramp
down, respectively, relative to the TXST signal. In addition, user data is gated
into the GMSK modulator while TXST is high. While TXST is low, G_DEF is
gated into the modulator.
expires in serial mode will be filled with G_DGF as opposed to loading data
from the FIFO or serial interface. This is used in serial mode with MS, as the
system needs to know to fill the first 16 bits with the default as the first MS
is blanked. The 16 bits occur only on the first burst of a multiburst transmis-
sion.
ramping to the next power level. Between bursts, the ramp down is initiated
by TXST falling. The ramp up is initiated with TXST rising.
