EOC interrupt triggered when AWDIE and EOCIE set to ‘1’
Description
When the analog watchdog is enabled and AWDIE and EOCIE are both set to ‘1’, the ADC
interrupt should only be triggered when the conversion result exceeds one of the analog
watchdog thresholds (see table 79 in the STM8A reference manual RM0009).
However, for the devices covered by this datasheet, the interrupt is triggered after each
conversion, thus leading to a high interrupt load.
Workaround
Set AWDIE to ‘1’ and EOCIE to ‘0’ instead and stop the conversions inside the ISR by
resetting the CONT bit. However the latest conversion result having triggered the watchdog
may be overwritten.
