27.5.2.9 DFlash User Multiple Input Signature Register 0 (DFLASH_UMISR0)
The DFLASH_UMISR0 provides a means to evaluate the Array Integrity.
The DFLASH_UMISR0 represents the bits 31:0 of the whole 144 bits word (2 Double Words including
ECC).
The DFLASH_UMISR0 is not accessible whenever DFLASH_MCR[DONE] or DFLASH_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.
