Bit
[31:6] Read undefined. Write as zero.
[5:0] Secure RAM region size in 4KB steps.
0x00000000 = no secure region
0x00000001 = 4KB secure region
0x00000002 = 8KB secure region
...
0x0000001F = 128KB secure region
0x00000020 or above sets the entire RAM to secure
regardless of size
Bit
[31:8] Read undefined.
[7:0] Show the status of the decode protection output:
0 = Decode region corresponding to the bit is secure
1 = Decode region corresponding to the bit is non-secure
There is one bit of the register for each protection output,
eight outputs are implemented as standard.
