Register description
Control/status register (ADCCSR)
Reset value: 0000 0000 (00h)
Bit 7 = EOC End of Conversion bit
This bit is set by hardware. It is cleared by hardware when software reads the ADCDRH
register or writes to any bit of the ADCCSR register.
0: Conversion is not complete
1: Conversion complete
Bit 6 = SPEED ADC clock selection bit
This bit is set and cleared by software. It is used together with the SLOW bit to
configure the ADC clock speed. Refer to the table in the SLOW bit description
(ADCDRL register).
Bit 5 = ADON A/D Converter on bit
This bit is set and cleared by software.
0: A/D converter is switched off
1: A/D converter is switched on
Bits 4:3 = Reserved. Must be kept cleared.
Bits 2:0 = CH[2:0] Channel Selection
These bits select the analog input to convert. They are set and cleared by software.
