NXP Semiconductors MPC5606S - User Multiple Input Signature Register 1 (UMISR1)

Flash Memory
MPC5606S Microcontroller Reference Manual, Rev. 7
Freescale Semiconductor 577
The UMISR0 Register is not accessible whenever MCR.DONE or UT0.AID are low: reading returns
indeterminate data while writing has no effect.
17.2.6.19 User Multiple Input Signature Register 1 (UMISR1)
The Multiple Input Signature Register provides a mean to evaluate the Array Integrity.
The User Multiple Input Signature Register 1 represents the bits 63-32 of the whole 144 bits word (2
Double Words including ECC).
The UMISR1 Register is not accessible whenever MCR.DONE or UT0.AID are low: reading returns
indeterminate data while writing has no effect.

Field 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.
