can be set by the user to enable SRQ (Service request) in case a condition change occurs. Event
registers latch condition registers state if the corresponding Enable registers are set to logical one.
Event registers remain set (latched) until the user reads the register, reading the register clears its
values until the next event.
NOTE
Event register does not specify that a single condition event has occurred. In the period where an
event has occurred and user has read the value, the Condition register might change its value
multiple times.
7.3.2 Questionable Group (Fault Register) Structure
Questionable group fault register holds a snapshot of the actual faults state of the power supply at
a present time. If a fault occurs, the corresponding bit is set. If a fault is removed, the
corresponding bit is cleared. Some of the faults might quickly change their state (clear faults)
before the controlling PC detects it. Events can be stored in the Event register if the Enable register
allows it. Refer to General Status Register Commands (section 5.10.9) set. Table 7-7 describes bit
configuration of the questionable group fault register.
