generated) invalidated a locked cache line. Note that the lock bit for that line is cleared whenever the line is
invalidated. This bit can be cleared only by software.
0 The cache has not encountered a dcbi snoop that invalidated a locked line.
1 The cache has encountered a dcbi snoop that invalidated a locked line.
(Data) Cache unable to lock. Sticky bit set by hardware and cleared by writing 0 to this bit location.
0 Indicates a lock set instruction was effective in the cache
1 Indicates a lock set instruction was not effective in the cache
(Data) Cache lock overflow. Sticky bit set by hardware and cleared by writing 0 to this bit location.
0 Indicates a lock overflow condition was not encountered in the cache
1 Indicates a lock overflow condition was encountered in the cache
Address broadcast enable. The e500 broadcasts cache management instructions (dcbst, dcblc
(CT = 1), icblc (CT = 1), dcbf, dcbi, mbar, msync, tlbsync, icbi) based on ABE. ABE must be set to
allow management of external L2 caches.
