17.2.6.26 Non-Volatile System Censoring Information 1 register (NVSCI1)
The Non-volatile System Censoring Information 1 register stores the 32 MSB of the Censorship Control
Word of the SoC.
The NVSCI1 is a non-volatile register located in Shadow block: it is read during the reset phase of the flash
module and the protection mechanisms are activated consequently.
The parts are delivered uncensored to the user.

Field Description
0:15 SC15-0: Serial Censorship control word 15-0 (Read/Write)
These bits represent the 16 LSB of the Serial Censorship Control Word (SCCW).
If SC15-0 = 0x55AA and NVSCI1 = NVSCI0 the Public Access is disabled.
If SC15-0  0x55AA or NVSCI1  NVSCI0 the Public Access is enabled.
16:31 CW15-0: Censorship control Word 15-0 (Read/Write)
These bits represent the 16 LSB of the Censorship Control Word (CCW).
If CW15-0 = 0x55AA and NVSCI1 = NVSCI0 the Censored mode is disabled.
If CW15-0  0x55AA or NVSCI1  NVSCI0 the Censored mode is enabled.
