Field Description
This field concatenated with leading zeros plus the FlexNVM base address indicates the first invalid
address of the FlexNVM (flash block 1).
For example, if MAXADDR1 = 0x20 the first invalid address of flash block 1 is 0x4_0000 + 0x1000_0000 .
This would be the MAXADDR1 value for a device with 256 KB FlexNVM.
