ADC Result Data Registers – ADCH and ADCL
ADLAR = 0
In case of trig on PSCnASY event, there is no flag. So, if ADSSEN is reset, a conversion will start each
time the trig event appears and the previous conversion is completed ..
Table 18-6.
When an ADC conversion is complete, the conversion results are stored in these two result data registers.
When the ADCL register is read, the two ADC result data registers can’t be updated until the ADCH reg-
ister has also been read.
Consequently, in 10-bit configuration, the ADCL register must be read first before the ADCH.
Nevertheless, to work easily with only 8-bit precision, there is the possibility to left adjust the result
thanks to the ADLAR bit in the ADCSRA register. Like this, it is sufficient to only read ADCH to have
the conversion result.
