Functional Description and Application Information
4.2.3.1.3
4.2.3.2
For device options with reduced number of wake up inputs (Lx), the following considerations are to be made.
4.2.3.2.1
4.2.3.2.2
The Lx - Bit for the not available Lx input in the Lx Status Register must be ignored.
The Lx Control register for the not available Lx input must be written 0.
A not available Lx input can not be selected as Wake-up Source and must have its LxWE bit set to 0.
The Wake-up Source Register for not available Lx inputs must be ignored.
The Conversion Control Register for the not available Lx analog input (3…8) must always be written 0.
