FUNCTIONAL DESCRIPTION
The calibrated measurement value calculations
need to be done outside in the host system by
utilizing the stored calibration coefficient data.
register. Despite of on chip power on reset (POR)
circuit it is recommended to reset the device
manually after every power up to guarantee proper
register settings after any VDD rise conditions.
To avoid modification of the EEPROM by mistake
there is an EEPROM write enable bit (EWE) in the
EEPROM Control Register (E6/66HEX) which needs
to be set high (1) before any changes can be done
to the EEPROM.
The EOC pin indicates if a conversion has finished
and the result is ready to be read from the memory
via the serial interface. Using the EOC signal is not
necessary since it is alternatively possible to wait at
least maximum conversion time period before
reading out the result.
The XCLR pin can be used to hard reset the device
including the serial communication. However device
reset is possible also via serial bus using the reset
