7.2.4 Standard Event Status Group Structure
Standard event status group latches error groups. Power switch on and operation complete events
status might quickly change its condition before the controlling PC detects it. Events can be stored
in the Event register if the Enable register allows it. Refer to Common Commands Group (section
5.13) for standard event status group commands. Table 9-3 describes bit configuration of the
standard event status register group. Standard event status group registers are cleared when read,
refer to *ESR? Command (section 5.13). To program specific bits in the standard event status
group enable register, refer to *ESE command (section 5.13). If *PSC is set, Enable register is
cleared at power supply power on.
