27.5.1.17 CFlash Nonvolatile System Censorship Control 1 register (NVSCC1)
The NVSCC1 register stores the 32 MSB of the Censorship Control Word of the device.
The NVSCC1 is a nonvolatile register located in the Shadow sector: it is read during the reset phase of the
flash memory module and the protection mechanisms are activated consequently.
The parts are delivered uncensored to the user.

Field Description
SC[15:0] Serial Censorship control word, bits 15-0
These bits represent the 16 LSB of the Serial Censorship Control Word (SCCW).
If SC15-0 = 0x55AA and NVSCC1 = NVSCC0 the Public Access is disabled.
If SC15-0
0x55AA or NVSCC1 NVSCC0 the Public Access is enabled.
CW[15:0] Censorship control Word, bits 15-0
These bits represent the 16 LSB of the Censorship Control Word (CCW).
If CW15-0 = 0x55AA and NVSCC1 = NVSCC0 the Censored Mode is disabled.
If CW15-0
0x55AA or NVSCC1 NVSCC0 the Censored Mode is enabled.
