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.
