3) SSP Check

By starting this diagnostic program, the SSP setting for testing is
automatically performed and the SSP check is executed and the

The SSP check sets data for checking in the vacant space of the
SSP entry register, and deletes the data that is checked after com-
pletion of the test. Therefore, existing data is not changed by this
