Point
With this operation, the Error Clear operation is performed for the
SR-750.
Buffer Overflow Error and General Error are cleared, and the result
data within Result Data Available, Result Data Strobe and SR-750
are cleared.
When performing using the cyclic communication, the operation
will become the same by setting the Error Clear bit to ON.
