Description
0:31 DAI63-32: Data Array Input 63-32 (Read/Write)
These bits represent the input of odd word of ECC logic used in the ECC Logic Check. The DAI63-32
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.

Figure 17-16. User Multiple Input Signature Register 0 (UMISR0)
The Multiple Input Signature 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 UMISR0 Register is not accessible whenever MCR.DONE or UT0.AID are low: reading returns
indeterminate data while writing has no effect.

Description
0:31 MS031-000: Multiple input Signature 031-000 (Read/Write)
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 UMISR0 register.
