The UMISR1 Register is not accessible whenever MCR.DONE or UT0.AID are low: reading returns
indeterminate data while writing has no effect.

Description
0:31 MS063-032: Multiple input Signature 063-032 (Read/Write)
These bits represent the MISR value obtained accumulating the bits 63-32 of all the pages read from the
Flash Memory.
The MS can be seeded to any value by writing the UMISR1 register.

Figure 17-39. User Multiple Input Signature Register 2 (UMISR2)
The Multiple Input Signature Register provides a mean to evaluate the Array Integrity.
The User Multiple Input Signature Register 2 represents the bits 95-64 of the whole 144 bits word (2
Double Words including ECC).
The UMISR2 Register is not accessible whenever MCR.DONE or UT0.AID are low: reading returns
indeterminate data while writing has no effect.
