Table 123 Self-test log data structure   

The data structure contains the descriptor of Self-test that the device has performed. Each descriptor is 
24 bytes long and the self-test data structure is capable to contain up to 21 descriptors.   
After 21 descriptors has been recorded, the oldest descriptor will be overwritten with new descriptor. 
Self-test log pointer points the most recent descriptor. When there is no descriptor the value is 0. When 
there is descriptor(s) the value is 1 through 21.
