Data register High (ADCDRH)
Reset value: xxxx xxxx (xxh)
Bits 7:0 = D[9:2] MSB of Analog Converted Value
ADC Control/data register Low (ADCDRL)
Reset value: 0000 00xx (0xh)
Bits 7:4 = Reserved. Forced by hardware to 0.
Bit 3 = SLOW Slow mode bit
This bit is set and cleared by software. It is used together with the SPEED bit in the
ADCCSR register to configure the ADC clock speed as shown on the table below.
Bit 2 = Reserved. Forced by hardware to 0.
Bits 1:0 = D[1:0] LSB of Analog Converted value
