Status Registers Model from IEEE 488.2

Status Registers Model from IEEE 488.2

The IEEE 488.2 registers shown in the bottom rectangle of Figure 5-16 follow the IEEE 488.2 model for status registers. The IEEE 488.2 register only has enable registers for masking the summary bits. Figure 5-17 shows the details on the relationship between the mask/enable registers and the summary bits. Sections describing the bits for both registers will follow Figure 5-17.
