9.6 Standard Event Status Group 9.6.1 Register Functions

This group consists of an Event register and an Enable register that are programmed by COMMON commands. The Standard Event register latches events relating to interface communication status. It is a read-only register that is cleared when read. The Standard Event Enable register functions similarly to the Enable registers of the Operation and Questionable status groups. 9.6.2 Register Commands The common *ESE command programs specific bits in the Standard Event Status Enable register. Because the power supply implements *PSC, the register is cleared at power on if *PSC = 1.

*ESR? reads the Standard Event Status Event register. Reading the register clears it.
