AT90PWM216/316
ADC Result Data Registers – ADCH and ADCL
ADLAR = 0
Table 21-6.
1.
.
Table 21-7.
1.
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 register 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.
