27.5.2.10 DFlash User Multiple Input Signature Register 1 (DFLASH_UMISR1)
The DFLASH_UMISR1 provides a mean to evaluate the Array Integrity.
The DFLASH_UMISR1 represents the bits 63:32 of the whole 144 bits word (2 Double Words including
ECC).
The DFLASH_UMISR1 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[31:0] Multiple input Signature, bits 31–0
These bits represent the MISR value obtained accumulating the bits 31:0 of all the pages read from the flash
memory.
The MS can be seeded to any value by writing the DFLASH_UMISR0 register.
