27.5.2.12 DFlash User Multiple Input Signature Register 3 (DFLASH_UMISR3)
The DFLASH_UMISR3 provides a mean to evaluate the Array Integrity.
The DFLASH_UMISR3 represents the bits 127:96 of the whole 144 bits word (2 Double Words including
ECC).
The DFLASH_UMISR3 is not accessible whenever DFLASH_MCR[DONE] or DFLASH_UT0[AID] are
low: reading returns indeterminate data while writing has no effect.

Field Description
MS[95:64] Multiple input Signature, bits 95-64
These bits represent the MISR value obtained accumulating the bits 95:64 of all the pages read from
the flash memory.
The MS can be seeded to any value by writing the DFLASH_UMISR2.
