The Status Byte Register is the summary-level register in the status reporting structure. It contains summary bits that monitor activity in the other status registers and queues as shown in Figure 3-7.

The Status Byte Register is a live register— its summary bits are set TRUE or FALSE (one or zero) by the presence or absence of the condition which is being summarized.

The Status Byte Register can be read with either a serial poll or the *STB? query.

The Status Byte Register is altered only when the state of the overlying status data structures is altered.

The entire Status Byte Register can be cleared by sending the *CLS command, by itself in a program message, to the Counter.

Table 3-4 lists the Status Byte Register bits and briefly describes each bit.
