Operation Event Register
You can program the bits in the Operation Condition and Operation Event Status registers to be
cleared or set when an event occurs.
When an enabled Operation Event Register bit is set, the corresponding bit B7 (OSB) of the Status
Byte Register is set.
When an enabled Operation Event Register bit is set (because the enabled event occurs), the
corresponding bit B7 (OSB) of the Status Byte Register is set. The corresponding Operation Event
Register Condition register reflects the present status of the instrument, so it will be set while the
event occurs.
You can use the following commands to read and set bits contained in the Operation Event Register.

The instrument returns a decimal value that corresponds to the binary-weighted sum of all bits set in the register.
You can use a copy of the following table to record settings for your instrument.
