Transition filters are unaffected by *CLS or queries. Transition filters are
set to default values by :STATus:PRESet and power-on.
To write to the Operation Status transition filter registers use:
:STATus:OPERation:PTRansition
:STATus:OPERation:NTRansition
To read these registers use:
:STATus:OPERation:PTRansition?
:STATus:OPERation:NTRansition?
Event Register
An event register captures changes in conditions.
An event register bit (event bit) is set TRUE when an associated event
occurs. These bits, once set, are “sticky.” That is, they cannot be cleared
even if they do not reflect the current status of a related condition, until
they are read.
