offset;
// Offset from byte 0

// Size in bytes
};
typedef struct _NVM_XFER NVM_XFER, *PTR_NVM_XFER;
Note: Use the McbReadDataMem function to read data from scratch pad. The offset term in the data
structure determines the offset address relative to the NVM part. This command allows the host to
retrieve any portion or all of the current NVM contents.
Do not confuse access to this memory block with the portion of the global configuration data structure
that has a structure member that contains the shadow version. On boot data from the NVM part is
loaded into the global data structure for real time use by the software.
