Notes:  
6. See the last page of this specification for Group A subgroup testing information.  
7. BUSY and INT pins only.  
8. Duration of the short circuit should not exceed 30 seconds.  
9. At f=fMAX, address and data inputs are cycling at the maximum frequency of read cycle of 1/trc and using AC Test Waveforms input levels of GND to 3V.  
10. This parameter is guaranteed but not tested.
