27.5.1.10 CFlash User Multiple Input Signature Register 1 (CFLASH_UMISR1)
The CFLASH_UMISR1 provides a means to evaluate the Array Integrity.
The CFLASH_UMISR1 represents the bits 63:32 of the whole 144 bits word (2 Double Words including
ECC).
The CFLASH_UMISR1 is not accessible whenever CFLASH_MCR[DONE] or CFLASH_UT0[AID] are
low: reading returns indeterminate data while writing has no effect.

Field Description
MS0[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 CFLASH_UMISR0 register.
