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.
