Condition
Register The Questionable Status Condition Register
indicates the status of the power supply. If a bit
is set in the Condition register, it indicates that
the event is true. Reading the condition register
does not change the state of the condition
register.
PTR/NTR Filters The PTR/NTR (Positive/Negative transition)
register determines the type of transition
conditions that will set the corresponding bit in
the Event Registers. Use the Positive transition
filter to view events that change from false to
positive, and use the negative transition filter to
view events that change from positive to
negative.
Positive Transition 0→1
Negative Transition 1→0
Event Register The PTR/NTR Register will dictate the type of
transition conditions will set the corresponding
bits in the Event Register. If the Event Register
is read, it will be cleared to 0.
Enable Register The Enable register determines which Events in
the Event Register will be used to set the QUES
bit in the Status Byte Register.
