All of the other bits of this register are not used by the 1256. These
bits will return a value of 0 when read.
The Operation Status Enable Register enables individual bits to
pass through to the Operation Status Event Register. The bits of
the Operation Status Enable Register are ANDed with the bits of
the Operation Status Condition Register. If both bits are set, then
the corresponding bit in the Operation Status Event Register is set.
For example, if bits 1, 5, and 6 of the Operation Status Condition
Register are set, and bits 5 and 6 of the Operation Status Enable
Register are set, then bits 5 and 6 of the Operation Status Event
Register will be set.

armed, but is waiting for a trigger.
The TRIGGER:SOURCE command
may be used to select a trigger
source. If the trigger source is "BUS",
