Event enable registers
As Figure 14-1 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 14-7. For
details on programming and reading registers, see “Programming enable registers,”
page 14-5 and “Reading registers,” page 14-6.
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).
