especially during processing, are likely to return non-zero values for many bits between 0–57. The four
signals shown are those which are most likely to be of interest to the user.
The MDEU status register is read-only. Writing to this location results in address error being reflected in
the MDEU interrupt status register.

describes the MDEU status register fields.
MPC8544E PowerQUICC III Integrated Host Processor Family Reference Manual, Rev. 1
0 MDEU not halted
1 MDEU halted
Note: Because the error causing the MDEU to stop operating may be masked before reaching the interrupt
status register, the MDEU interrupt status register is used to provide a second source of information regarding
errors preventing normal operation.
00 No integrity check comparison was performed.
01 The integrity check comparison passed.
10 The integrity check comparison failed.
11 Reserved
Note: A passed or failed result is generated only if ICV checking is enabled.
Interrupt error. This status bit reflects the state of the ERROR interrupt signal, as sampled by the controller
interrupt status register
0 MDEU is not signaling error
1 MDEU is signaling error
Interrupt done. This status bit reflects the state of the DONE interrupt signal, as sampled by the controller
interrupt status register
0 MDEU is not signaling done
1 MDEU is signaling done
in the signal sampled by the appropriate channel.
0 Reset in progress
1 Reset done
Note: Reset done resets to 0, but has typically switched to 1 by the time a user checks the register, indicating
the EU is ready for operation.
Reserved
Halt. Indicates that the MDEU has halted due to an error.
Integrity check comparison result
Reset done. This status bit, when high, indicates that MDEU has completed its reset sequence, as reflected
