PCM600.
The following settings can be done for the stub protection.
GlobalBaseSel: Selects the global base value group used by the function to define
IBase, UBase and SBase as applicable.
Operation: Off/On
ReleaseMode: This parameter can be set Release or Continuous. With theRelease
setting the function is only active when a binary release signal RELEASE into the
