Reserved, should be cleared.
Internal debug mode
0 Debug interrupts are disabled. No debug interrupts are taken and debug events are not logged.
1 If MSR[DE] = 1, the occurrence of a debug event or the recording of an earlier debug event in the DBSR
Programming note: Software must clear debug event status in the DBSR in the debug interrupt handler
when a debug interrupt is taken before re-enabling interrupts through MSR[DE]. Otherwise, redundant debug
interrupts are taken for the same debug event.
Reset. The e500 implements these bits as follows:
0 x Default (No action)
1 x Causes a hard reset if MSR[DE] and DBCR0[IDM] are set. Always cleared on subsequent cycle. This
Instruction completion debug event enable
0 ICMP debug events are disabled
1 ICMP debug events are enabled
Note: Instruction completion does not cause an ICMP debug event if MSR[DE] = 0.
Branch taken debug event enable
0 BRT debug events are disabled
1 BRT debug events are enabled
Note: Taken branches do not cause a BRT debug event if MSR[DE] = 0.
Interrupt taken debug event enable. This bit affects only noncritical interrupts.
0 IRPT debug events are disabled
1 IRPT debug events are enabled
0 TRAP debug events cannot occur
1 TRAP debug events can occur
