Enable Register
The enable register specifies the bits in the event register that can
generate a summary bit. The instrument logically ANDs corresponding bits
in the event and enable registers and ORs all the resulting bits to obtain a
summary bit. Enable registers are read- write. Querying an enable register
does not affect it.
An Example Sequence
Figure 1- 8 illustrates the response of a single bit position in a typical
status group for various settings. The changing state of the condition in
question is shown at the bottom of the figure. A small binary table shows
the state of the chosen bit in each status register at the selected times T1
to T5.
