Bits Name
58 HALT Halt. Indicates that the AESU has halted due to an error.
0 AESU not halted
1 AESU halted
Note: Because the error causing the AESU to stop operating may be masked before reaching the interrupt
status register, the AESU interrupt status register (AESUISR) is used to provide a second source of
information regarding errors preventing normal operation.
59–60 ICR Integrity check result
00 No integrity check was performed.
01 The integrity check passed.
10 The integrity check failed.
11 Reserved
61 IE Interrupt error. This status bit reflects the state of the ERROR interrupt signal, as sampled by the controller
interrupt status register
0 AESU is not signaling error
1 AESU is signaling error
62 ID Interrupt done. This status bit reflects the state of the DONE interrupt signal, as sampled by the controller
interrupt status register
0 AESU is not signaling done
1 AESU is signaling done
63 RD Reset done. This status bit, when high, indicates that AESU has completed its reset sequence, as reflected
in the signal sampled by the 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.
14.4.3.6 AESU Interrupt Status Register (AESUISR)
The AESU interrupt status register (AESUISR), shown in
if those errors are not masked, through the AESU interrupt control register (AESUICR).
