The UMISR2 Register is not accessible whenever MCR.DONE or UT0.AID are low: reading returns
indeterminate data while writing has no effect.

Description
0:31 MS095-064: Multiple input Signature 095-064 (Read/Write)
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 UMISR2 register.

Figure 17-19. User Multiple Input Signature Register 3(UMISR3)
The Multiple Input Signature Register provides a mean to evaluate the Array Integrity.
The User Multiple Input Signature Register 3 represents the bits 127-96 of the whole 144 bits word (2
Double Words including ECC).
The UMISR3 Register is not accessible whenever MCR.DONE or UT0.AID are low: reading returns
indeterminate data while writing has no effect.
