(Not applicable to N-Class and A-Class ) NVM stores system activity parameters, including a circular queue
of the last six ISL utilities executed, which is useful as a diagnostic aid in the event of a system crash or

NVM contains initialization information in a 92-byte block starting at decimal byte address 36. NVM stores
this information as shown in Figure C-2.
