MESI States and Cache Status Flags

The data cache logic of Power Architecture cores is described as states of the MESI protocol. The debugger 
displays the cache state using the cache line status flags valid, dirty and shared. The debugger also displays 
additional status flags (e. g. locked) which can not be mapped to any of the MESI states.

State translation table:

Using Cache Lines as SRAM Extension

Some e200 cores (e200z6, e200z650, e200z750, e200z760) allow using locked cache lines as additional 
SRAM. The cache lines are enabled and locked to an unused address. In this case the debugger might fail 
to display the contents in cache (bus error) if the debugger is not configured / used as described below.

If the cache lines are used as data memory, ensure that 

SYStem.Option DCREAD

 is set to ON (default).

l or ll

Way locked.
MPC55XX with unified cache:
--: not locked
I-: locked for instructions globally through L1CSR[WID]
-D: locked for instructions globally through L1CSR[WID]

MPC5XXX with I/D-Cache (harvard):

L: locked

sa ua

Supervisor (sa)/user (ua) access protection:

Lockout state.
Cache lines with tag errors or data errors will have this lockout 
indicator set. MPC57XX/SPC57X/58X only.
