Sensor Digital Controller
The main features of the sensor digital controller block are:
Before any A/D conversion, the configuration of the sensors must be stored in the register file at addresses
from #12 to #1A. Each sensor has its configuration stored in EEPROM. Depending on the selected sensor,
the appropriate data will be copied from EEPROM to the register file.
The configuration of the selected sensor is automatically loaded from EEPROM when:
The configuration of the selected sensor is not automatically loaded from EEPROM when:
