Changing the conversion channel
The application can change channels during conversion. When software modifies the
CH[3:0] bits in the ADCCSR register, the current conversion is stopped, the EOC bit is
cleared, and the A/D converter starts converting the newly selected channel.
9.5.4
Low-power modes
Note that the A/D converter may be disabled by resetting the ADON bit. This feature allows
reduced power consumption when no conversion is needed.
9.5.5
Interrupts
None.

Register description
Control/status register (ADCCSR)
Reset value: 0000 0000 (00h)
R
Bit 7 = EOC End of Conversion
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
This bit is set and cleared by software. It is used together with the MAX_SPEED bit to
select the ADC frequency. Refer to Table 49
Bit 5 = ADON A/D Converter on
This bit is set and cleared by software.
0: Disable ADC and stop conversion
1: Enable ADC and start conversion
Table 48.

Description
Wait
No effect on A/D converter
Halt
A/D Converter disabled.
After wakeup from Halt mode, the A/D converter requires a stabilization time tSTAB (see
Electrical Characteristics) before accurate conversions can be performed.
