10-bit A/D converter (ADC)
262/324
Bit 7 = EOC End of Conversion
This bit is set by hardware. It is cleared by software reading the ADCDRH register or writing
to any bit of the ADCCSR register.
Bit 6 = SPEED A/D clock selection
This bit is set and cleared by software.
Table 91.
Bit 5 = ADON A/D Converter on
This bit is set and cleared by software.
Bit 4 = SLOW A/D Clock Selection
This bit is set and cleared by software. It works together with the SPEED bit. Refer to
Table
Bits 3:0 = CH[3:0] Channel Selection
These bits are set and cleared by software. They select the analog input to convert.
Table 92.
