Continuous scan mode
In this mode, the ADC channels starting from ANI0 to the one specified by the
ADA0S register are sequentially converted and the conversion results are
stored in the ADCR0n registers.
In continuous scan mode power-fail comparison is performed only on ANI0.
After each conversion of ANI0, the higher 8 bits of conversion result in
ADA0CR0H0 is compared with the value of the ADA0PFT register.
If the result of power-fail comparison matches the condition set by the
ADA0PFM.ADA0PFC bit, INTAD is generated.
In any case conversion of the remaining ADC channels continuous.
Thus it is possible to catch a snapshot of the other analog inputs ANIn in case
of power-fail.
