I want to overwrite the ADC factory calibration coefficients. Do I have to do a
calibration every
time I run my software.


Every time the ADuC834 is reset, the factory calibrated calibration
coefficients are downloaded to
the calibration registers in the SFR space. Hence these SFRs must be
overwritten with your
individual calibration coefficients. To avoid having to do a calibration every
time that the
ADuC834 powers up it is often easier to write the calibration coefficients to
the Flash/EE data
memory space. Then in your own initialization the coefficients can simply be
read from the
flash/EE data memory and the calibration process does not have to be repeated.
