The Status Byte Register

NOTE

As shown in Figure 4-1, the Status Byte register is the highest-level register in the status structure. This register contains bits which summarize information from the other status groups.

The bits in the other status group registers must be specifically enabled to be reported in the Status Byte register. Refer to "Unmasking Standard Event Status Bits" (later in this chapter) for more information.
