27.5.1.12 CFlash User Multiple Input Signature Register 3 (CFLASH_UMISR3)
The CFLASH_UMISR3 provides a mean to evaluate the Array Integrity.
The CFLASH_UMISR3 represents the bits 127:96 of the whole 144 bits word (2 Double Words including
ECC).
The CFLASH_UMISR3 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[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 CFLASH_UMISR2.
