Details
This attribute is used to read the service request event register, which is returned as a numeric value. Reading
this register returns a value. The binary equivalent of the value of this attribute indicates which register bits are
set. In the binary equivalent, the least significant bit is bit B0, and the most significant bit is bit B7. For example, if
a value of
1.02
(which is 129) is read as the value of this register, the binary equivalent is 1000 0001.
This value indicates that bit B0 and bit B7 are set.
