258 / 380 page  258 8059D–AVR–11/09 ATmega1284P 21.9.3 ADCL and ADCH – The ADC Data Register ADLAR = 0 ADLAR = 1 When an ADC conversion is complete, the result is found in these two registers. If differential channels are used, the result is presented in two’s complement form. When ADCL is read, the ADC Data Register is not updated until ADCH is read. Consequently, if the result is left adjusted and no more than 8-bit precision is required, it is sufficient to read ADCH. Otherwise, ADCL must be read first, then ADCH. The ADLAR bit in ADMUX, and the MUXn bits in ADMUX affect the way the result is read from the registers. If ADLAR is set, the result is left adjusted. If ADLAR is cleared (default), the result is right adjusted. • ADC9:0: ADC Conversion Result These bits represent the result from the conversion, as detailed in ”ADC Conversion Result” on page 253. 21.9.4 ADCSRB – ADC Control and Status Register B 10 0 16 10 1 32 11 0 64 11 1 128 Table 21-5.
