0 Debug interrupts are disabled.
1 Debug interrupts are enabled if DBCR0[IDM] = 1.
Reserved, should be cleared.
Instruction address space
0 The processor directs all instruction fetches to address space 0 (TS = 0 in the relevant TLB entry).
1 The processor directs all instruction fetches to address space 1 (TS = 1 in the relevant TLB entry).
Data address space
0 The processor directs data memory accesses to address space 0 (TS = 0 in the relevant TLB entry).
1 The processor directs data memory accesses to address space 1 (TS = 1 in the relevant TLB entry).
Reserved, should be cleared.
statistics to be gathered only during execution of the marked process. MSR[PR] and MSR[PMM] together define
a state that the processor (supervisor or user) and the process (marked or unmarked) may be in at any time. If
this state matches an individual state specified in the PMLCax, the state for which monitoring is enabled,
counting is enabled.
