STM8L1526-EVAL IDD Halt mode measurement timing diagram
Ru n
The Halt mode measurement procedure can be used in Halt mode and slow or fast active
Halt modes if the IDD current does not exceed 12 uA else the Run measurement procedure
should be used up to 12 mA.
Comparator
Three I/Os are used to implement a comparator feature to be used as low precision ADC in
Figure
