IF_FILT_RESET_

CNT

R/W

15:0

IF filter peak detector reset

interval

h0000

The number of 3 MHz

clock cycles between the

reset pulses to the IF filter

peak detector.

140

AUX_ADC_START

3:0

Start signal from FSM

AUX ADC mux selection

from FSM

h0000

141

AUX_ADC_START

R/W

3:0

Enable manual start

Manual start

AUX ADC mux selection

h0000

For starting an AUX ADC

measurement manually.

The start bit is self-

clearing.

142

AUX_ADC_DATA

7:0

AUX ADC Data

h0000

Data from the AUX ADC.

15:8

7:5

4:0

Settling time

Not used

Measurement time

h1010

u8.0

u5.0

Specified in 3 MHz clock

cycles.

151

SJC_ORIGIN

R/W

12:8

7:5

4:0

Origin of Q scaling

Not used

Origin of I scaling

h0000

s4.0

Center of scan matrix.

152

SJC_CONTROL

R/W

11:8

6:4

Scan size

Not used

Step size

Enable rx_start automatically

Use current settings as origin

Reduce gain

Trigger scan

h0110

u4.0

u3.0

Scan size: number of

evaluation points around

the origin. Set to one to get

a 3x3 matrix. Not possible

to program it to 0.

Step size: when set to one

the finest grid is used;

larger settings result in a

coarser grid. Not possible

to program it to 0.

Instead of taking the origin

from register h151 the

current setting (reg h154)

can be used as origin if bit

2 is set.

When the reduce gain bit

is set the RX data path

gain is automatically

temporarily switched to the

SJC gain settings

(register 0x451 as

opposed to the normal

gain settings defined by

The trigger bit is self-

clearing.

153

SJC_BIAS_

OFFSET

R/W

7:4

3:0

Q bias offset

I bias offset

h0000

s3.0

Offset applied to SJC

current bias.

154

SJC_SCALING_

OUT

12:8

s4.0

Returned scaling values.

155

SJC_SCALING_

VAL

15:12

Qp scaling

Qn scaling

Ip scaling

In scaling

u4.0

Returned scaling values in

analog notation.
