Enable override

(dcrem_open)

(mixer_lc_load)

Override value

(dcrem_open_dc)

Override value (dcrem_short)

Override value (dcrem_open)

h0000

Override register for the

DC removal signals.

MIXER_IFLNA_

INTERF

R/W

15:4

1:0

dcrem_short pulse width

Not used

Enable external LC mixer

load (mixer_load_select)

Select IF-LNA input path

(dcrem_select)

h0000

The dcrem_short pulse

width is specified in

48 MHz periods. When it is

set to zero no pulse is

generated.

IF-LNA input path:

0,1: External capacitor

2: Internal DC Path

3: Nothing connected.

130

ADC_OD_THRES

R/W

4:0

ADC input overdrive

threshold

h000F

The number of

consecutive samples of

the same value before the

“ADC overdriven” interrupt

is issued.

Specified in 48 MHz clock

cycles.

131

IFLNA_TH_CNT

R/W

15:0

IF LNA too high threshold

hFFFF

IF LNA too high count.

This determines how many

3 MHz clock cycles the too

high signal from the peak

detector needs to be

asserted before asserting

if_lna_too_high.

132

IFLNA_TL_CNT

R/W

15:0

IF LNA too low threshold

hFFFF

IF LNA too low count. This

determines how many

3 MHz clock cycles the too

low signal from the peak

detector needs to be

asserted before asserting

if_lna_too_low.

133

IFLNA_RESET_

CNT

R/W

15:0

IF LNA peak detector reset

interval

h0000

The number of 3 MHz

clock cycles between the

reset pulses to the IF LNA

peak detector.

134

IF_FILT_TH_CNT

R/W

15:0

IF filter too high threshold

hFFFF

IF filter too high count.

This determines how many

3 MHz clock cycles the too

high signal from the peak

detector needs to be

before asserting

if_filt_too_high.

135

IF_FILT_TL_CNT

R/W

15:0

IF filter too low threshold

hFFFF

IF filter too low count. This

determines how many

3 MHz clock cycles the too

low signal from the peak

detector needs to be

before asserting

if_filt_too_low.
