SysSWLock
Address:
0x8093_00C0 - Read/Write
Default:
0x0000_0000
Definition:
Syscon Software Lock Register. Provides software control port for all Syscon
locked registers. Writing the LOCK field to 0xAA opens the lock. Reading the
register will return 0x0000_0001 when the lock is open, and all zeros when the
lock is closed (locked).
Bit Descriptions:
RSVD:
Reserved. Unknown During Read.
LOCK:
Lock code value. This field must be written to a value of
0xAA to open the software lock. Reads 0x01 when the
lock is open, 0x00 when the lock is closed.
