VAMBIENT is copied from Data
EEPROM location, V90 is copied
from factory-calibrated location
The factory-calibrated value (V90)
is within range ?
Execute the calibration
routine user-calib()
Avg_slope, V90 = Default values
Execute ‘HALT’ instruction to
enter Low power mode
Avg_slope = V90 - VAMBIENT/T90 - TAMBIENT
