The *ESR? query returns the contents of the Standard Event Status Register. When
you read the Event Status Register, the value returned is the total bit weights of all
of the bits that are high at the time you read the byte. Reading the register clears
the Event Status Register.
The following table shows bit weight, name, and condition for each bit.
