Description
SC[31:16]
Serial Censorship control word 31-16 (Read/Write)
These bits represent the 16 MSB 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[31:16] Censorship control Word 31-16 (Read/Write)
These bits represent the 16 MSB 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.

1 _{See device memory map table for base address information of shadow flash.}
2 _{Reset values labeled “X” are loaded from the NVLML value which is preprogrammed at the factory. The default}
value from the factory for this register is 0xXXXX_XXXX. The default value can be reprogrammed by the user.
The Nonvolatile User Options Register contains configuration information for the user application.
The NVUSRO register is a 64-bit register, of which the 32 most significant bits 63:32 are ‘don’t care’ and
eventually used to manage ECC codes.
