27.5.1.9 CFlash User Multiple Input Signature Register 0 (CFLASH_UMISR0)
The CFLASH_UMISR0 register provides a mean to evaluate the Array Integrity.
The User Multiple Input Signature Register 0 represents the bits 31:0 of the whole 144 bits word (2 Double
Words including ECC).
The CFLASH_UMISR0 Register is not accessible whenever CFLASH_MCR[DONE] or
CFLASH_UT0[AID] are low: reading returns indeterminate data while writing has no effect.

Field Description
DAI[63:32] Data Array Input, bits 63–32
These bits represent the input of odd word of ECC logic used in the ECC Logic Check. Bits
DAI[63:32] correspond to the 32 array bits representing Word 1 within the double word.
0: The array bit is forced at 0.
1: The array bit is forced at 1.
