Explanation The bit 1 and bit 6 of the standard event status register are not used and are always
treated as 0; therefore, the range of <value> are the decimal numbers corresponding to
the binary numbers X0XXXX0X (X is 1 or 0).
Return

The query returns an integer which equals the sum of the weights of all the bits that have
already been set in the register.
