Register description
Control/status register (ADCCSR)
Read/Write (Except bit 7 read only)
Reset Value: 0000 0000 (00h)
Bit 7 = EOC End of Conversion
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
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.
Bit 5 = ADON A/D Converter on
This bit is set and cleared by software.
0: A/D converter and amplifier are switched off
1: A/D converter and amplifier are switched on
Bits 4:3 = Reserved. Must be kept cleared.
Bits 2:0 = CH[2:0] Channel Selection
These bits are set and cleared by software. They select the analog input to convert.
