AS39513 − Detailed Description

TV1TRIM[2:0] – Signed binary value. Trims the ADC reference

voltage V1 used during temperature and battery

measurements. See the section Analog to Digital Conversion

for more details.

TV1SET[2:0] – Reference levels for the ADC during temperature

measurements. The condition TV2SET ≥ TV1SET-1 must be

fulfilled to ensure the ADC input range V2-V1 is positive.

Note if the temperature range is changed the temperature

sensor will need recalibration. See the section Analog to Digital

Conversion for more details.

TV2TRIM[2:0] – Signed binary value. Trims the ADC reference

voltage V2 used during temperature and battery

measurements. See the section Analog to Digital Conversion

for more details.

TV2SET[2:0] – Reference levels for the ADC to use during

temperature measurements. The condition TV2SET ≥ TV1SET-1

must be fulfilled to ensure the ADC input range V2-V1 is

positive. Note if the temperature range is changed the

temperature sensor will need recalibration. See the section

Analog to Digital Conversion for more details.

TSMOFF[6:0] – Offset to use during temperature and battery

measurements. This value is a twos-compliment signed value.

It is sign-extended to 10 bits and added to the ADC result after

a temperature or battery measurement.

TSV1G – V1 ground setting (trf_gndv1_o) to use during

temperature measurements.

EV1TRIM[2:0] – Signed binary value. Trims the ADC reference

voltage V1 used during external sensor measurements. See the

section Analog to Digital Conversion for more details.

EV1SET[2:0] – Reference levels for the ADC to use during

external sensor measurements. The condition EV2SET ≥

EV1SET-1 must be fulfilled to ensure the ADC input range V2-V1

is positive. See the section Analog to Digital Conversion for

more details.

EV2TRIM[2:0] – Signed binary value. Trims the ADC reference

voltage V2 used during external sensor measurements. See the

section Analog to Digital Conversion for more details.

EV2SET[2:0] – Reference levels for the ADC to use during

external sensor measurements. The condition EV2SET ≥

EV1SET-1 must be fulfilled to ensure the ADC input range V2-V1

is positive. See the section Analog to Digital Conversion for

more details.

EXMOFF[6:0] – Offset to use during external sensor

measurements. This value is a twos-compliment signed value.

It is sign-extended to 10-bits and added to the ADC result after

an external sensor measurement.

EXV1G – V1 ground setting (trf_gndv1_o) to use during

external sensor measurements.

EXGAIN[1:0] – Multiplexer gain setting (mux_gain_o) to use

during external sensor measurements.
