End of conversion interrupt
An interrupt can be generated at the end of each conversion.
Analog watchdog interrupt
Moreover, another interrupt can be generated based on the upper or lower threshold limits
of the watchdog.
1-channel mode
Only the selected analog input is converted. At the end of this conversion, the overflow
status and result are stored in the control registers of the selected channel.
Scan mode
Up to six channels can be sequentially converted starting with Channel 0 and ending with
Channel 7. At the end of the conversion of each channel, the overflow status and result are
stored in the control register of the corresponding channel.
Single / continuous mode
Each main mode can run in either single or continuous mode.
In single mode, the conversion sequence for the analog channel input is performed one
single time.
In continuous mode, the conversion sequence is performed continuously until reset by
software.
Analog watchdog
The analog watchdog is used to generate an interrupt based on two programmable
threshold levels.
For each channel, when the level of the analog input exceeds upper and lower threshold
values, an interrupt is generated.
Low power modes
There are two low power modes available in order to reduce power consumption. In power
off mode there is no power consumption.
