Imprecise debug event. Set if MSR[DE] = 0 and a debug event causes its respective DBSR bit to be set.
Functions as write-one-to-clear.
Unconditional debug event. Set if an unconditional debug event occurred. Functions as
write-one-to-clear. If UDE (level sensitive, active low) is asserted, DBSR[UDE] is affected as follows:
MSR[DE]DBCR0[IDM]Action
X 0 No action.
0 1 UDE is set.
1 1 UDE is set and a debug interrupt is taken.
Most recent reset. Functions as write-one-to-clear. Undefined at power-on. The e500 implements
HRESET as follows:
0x No hard reset occurred since this bit was last cleared by software.
1x The previous reset was a hard reset.
Instruction complete debug event. Set if an instruction completion debug event occurred and
DBCR0[ICMP] = 1. Functions as write-one-to-clear.
Branch taken debug event. Set if a branch taken debug event occurred (DBCR0[BRT] = 1). Functions as
write-one-to-clear.
Interrupt taken debug event. Set if an interrupt taken debug event occurred (DBCR0[IRPT] = 1).
Functions as write-one-to-clear.
Trap instruction debug event. Set if a trap Instruction debug event occurred (DBCR0[TRAP] = 1).
Functions as write-one-to-clear.
Instruction address compare 1 debug event. Set if an IAC1 debug event occurred (DBCR0[IAC1] = 1).
Functions as write-one-to-clear.
Instruction address compare 2 debug event. Set if an IAC2 debug event occurred (DBCR0[IAC2] = 1).
Functions as write-one-to-clear.
Reserved, should be cleared
Data address compare 1 read debug event. Set if a read-type DAC1 debug event occurred
(DBCR0[DAC1] = 10 or 11). Functions as write-one-to-clear.
Data address compare 1 write debug event. Set if a write-type DAC1 debug event occurred
(DBCR0[DAC1] = 01 or 11). Functions as write-one-to-clear.
Data address compare 2 read debug event.Set if a read-type DAC2 debug event occurred
(DBCR0[DAC2] = 10 or 11). Functions as write-one-to-clear.
Data address compare 2 write debug event. Set if a write-type DAC2 debug event occurred
(DBCR0[DAC2] = 01 or 11). Functions as write-one-to-clear.
Return debug event. Set if a return debug event occurred (DBCR0[RET] = 1). Functions as
write-one-to-clear.
Reserved, should be cleared.
