Figure 3. Overview of Status Data Structure
Standard Event Status and Standard Event Status Enable Registers
The Standard Event Status Register (ESR) assigns events to specific bits (see Figure 3
and Table 5). When a bit in the ESR is set (for example, 1), the event that corresponds to
that bit has occurred since the register was last read or cleared. For example, if bit 3
(DDE) is set to 1, a device-dependent error has occurred.
The Standard Event Status Enable Register (ESE) is a mask register that allows the host
to enable or disable (mask) each bit in the ESR. When a bit in the ESE is 1, the
corresponding bit in the ESR is enabled. When any enabled bit in the ESR changes from
O to 1, the Standard Event bit in the Status Byte Register also goes to 1. When the ESR is
read (using the *ESR? command) or cleared (using the *CLS command), the Standard
Event bit in the Status Byte Register returns to 0.
