AGC_BLANK_MODE
0
R/W
Set the VGA blanking mode when switching out a gainstage
When
VGA_GAIN_OE
= 0:
0 : Blanking is performed when the AGC algorithm switches
out one or more 14dB gain stages.
1 : Blanking is never performed.
When
VGA_GAIN_OE
= 1:
Blanking is performed when
AGC_BLANK_MODE
=1

PEAKDET_CUR_BOOST
0
R/W
Doubles the bias current in the peak-detectors in-between the
VGA stages when set.
12:11
AGC_SETTLE_WAIT[1:0] 1
R/W
Timing for AGC to wait for analog gain to settle.
10:8
AGC_PEAK_DET_MODE
[2:0]
0
R/W
Sets the AGC mode for use of the VGA peak detectors:
Bit 2 : Digital ADC peak detector enable / disable
Bit 1 : Analog fixed stages peak detector enable /
disable
Bit 0 : Analog varliable gain stage peak detector enable /
disable
7:6
AGC_WIN_SIZE[1:0]
1
R/W
Window size for the accumulate and dump function in the
AGC.
0 : 8 samples
1 : 16 samples
2 : 32 samples
3 : 64 samples
5:0
AGC_REF[5:0]
20
R/W
Target value for the AGC control loop, given in 2 dB steps.
Reset value corresponds to approximately 25% of the ADC
dynamic range in reception.

MED2HIGHGAIN[4:0]
9
R/W
MED2HIGHGAIN sets the difference in the receiver
LNA/MIXER gain from medium gain mode to high gain mode,
used by the AGC for setting the correct frontend gain mode.
4:0
LOW2MEDGAIN[4:0]
10
R/W
LOW2MEDGAIN sets the difference in the receiver
LNA/MIXER gain from low gain mode to medium gain mode,
used by the AGC for setting the correct frontend gain mode.
