NXP Semiconductors MPC5606S - User Multiple Input Signature Register 3 (UMISR3)

Flash Memory
MPC5606S Microcontroller Reference Manual, Rev. 7
Freescale Semiconductor 621
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.
17.3.6.17 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.

Field 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.
