Status Byte (STB) and Service Request Enable Register (SRE)
The STatus Byte (STB) is already defined in IEEE 488.2. It provides a rough over-
view of the instrument status by collecting the pieces of information of the lower regis-
ters. A special feature is that bit 6 acts as the sum bit of the remaining bits of the status
byte.
