Comment:
This register is used to acquire a lock.
A non test controller (the master identifer of the access is NOT '15') read access attempts to
acquire a lock. This read access will return the result of the attempt as well as parameters of
the master which successfully acquired the lock.
A test controller (the master identifer of the access is '15') read access returns value of
LOCK_STATUS. A test controller write access attempts to acquire a lock (the write data value
is ignored and does not matter). A separate LOCK_STATUS read access is required to return
the result of the attempt.
Default:
0x0
