Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.

 pin can be raised to a HV level for RSWP
command execution. SCL and SDA inputs can be raised to the maximum limit, irrespective of V
