Software procedure
Refer to the control/status register (CSR) and data register (DR) in
definitions and to
ADC configuration
The total duration of the A/D conversion is 12 ADC clock periods (1/f
The analog input ports must be configured as input, no pull-up, no interrupt. Refer to the
«I/O ports» chapter. Using these pins as analog inputs does not affect the ability of the port
to be read as a logic input.
In the CSR register:

ADC conversion
In the CSR register:

When a conversion is complete:
●
●
●
A write to the CSR register (with ADON set) aborts the current conversion, resets the COCO
bit and starts a new conversion.

Low power modes
Table 44.
The A/D converter may be disabled by resetting the ADON bit. This feature allows reduced
power consumption when no conversion is needed and between single shot conversions.
WAIT
HALT
Select the CH[3:0] bits to assign the analog channel to be converted.
Set the ADON bit to enable the A/D converter and to start the first conversion. From this
time on, the ADC performs a continuous conversion of the selected channel.
The COCO bit is set by hardware.
No interrupt is generated.
The result is in the DR register and remains valid until the next conversion has ended.

A/D Converter disabled.
After wakeup from Halt mode, the A/D Converter requires a stabilization time
before accurate conversions can be performed.
