Appendix B: Register Details
reserved 13 rw 0x1 Reserved - always write with 1
PCFG_AES_FUSE 12 rw 0x0 (Lockable, see 0x004, bit 4)
This bit is used to select the AES key source
0 - BBRAM key
1 - eFuse key
User access to this bit is restricted.
The boot ROM will make the key selection and
lock this bit during the initial boot sequence.
This bit is only cleared by PS_POR_B reset.
PCFG_AES_EN 11:9 rw 0x0 (Lockable, see 0x004, bit 3)
This bit enables the AES engine within the PL.
The three bits need to be either all 0's or 1's, any
inconsistency will lead to security lockdown.
000 - Disable AES engine
111 - Enable AES engine
All others - Secure lockdown
User access to this bit is restricted.
The boot ROM will enable the AES engine for
secure boot and will always lock this bit before
passing control to user code.
This bit is only cleared by PS_POR_B reset.
SEU_EN 8 rw 0x0 (Lockable, see 0x004, bit 2)
This bit enables an automatic lockdown of the PS
when a PL SEU is detected.
0 - Ignore SEU signal from PL
1 - Initiate secure lockdown when SEU signal
received from PL
This bit is sticky, once set it can only be cleared
with a PS_POR_B reset.
SEC_EN 7 ro 0x0 (Lockable, see 0x004, bit 1)
This bit is used to indicate if the PS has been
booted securely.
0 - PS was not booted securely
1 - PS was booted securely
User access to this bit is restricted.
The boot ROM will set this bit when a secure boot
is initiated and will always lock the bit before
passing control to user code.
This bit is only cleared by PS_POR_B reset.
SPNIDEN 6 rw 0x0 (Lockable, see 0x004, bit 0)
Secure Non-Invasive Debug Enable
0 - Disable
1 - Enable
