7-16 Status Structure
Event enable registers
As Figure 7-1 shows, each status register set has an enable register. Each event register bit is
logically ANDed (&) to a corresponding enable bit of an enable register. Therefore, when an
event bit is set and the corresponding enable bit is set (as programmed by the user), the output
(summary) of the register will set to 1, which in turn sets the summary bit of the status byte
register.
The commands to program and read the event enable registers are listed in Table 7-5. For
details on programming and reading registers, see “Programming enable registers” and “Read-
ing registers”.
NOTE The bits of any enable register can be reset to 0 by sending the 0 parameter value
with the appropriate enable command (i.e. STATus:OPERation:ENABle 0).
