CFG2(17)
VDS
0
VLIF or DCR Select
0=VLIF
1=DCR
CFG2(16)
QINV
0
Inverts the Q signal path.
0=uninverted, normal polarity
1=inverted polarity
CFG2(15)
IQSWPI
0
Swaps the I and Q signal paths at the input to the digital VLIF processor.
0=normal, unswapped
1=swapped
CFG2(14)
IQSWPO
0
Swaps the I and Q signal paths at the baseband output of the digital VLIF pro-
cessor.
0=normal, unswapped
1=swapped
CFG2(13)
TRD
0
Transmit/Receive GPO Switch Control. If programmed to 1 then the functionality
described by TRDC_TX and TRDC_RX is activated. If programmed to zero
then the GPO pins follow the GPO programming at all times.
