The interrupt status register tracks the state of possible errors—if those errors are not masked—via the
PKEU interrupt control register. The definition of each bit in the PKEU interrupt status register is shown

PKEU Interrupt Status Register (PKEUISR)
Reserved
Zero. This bit reflects the state of the PKEU zero detect bit when last sampled. Only particular instructions within
routines cause zero to be modified, so this bit should be used with great care.
0 PKEU not halted
1 PKEU halted
Note: Because the error causing the PKEU to stop operating may be masked before reaching the interrupt
Reserved
Interrupt error. This status bit reflects the state of the ERROR interrupt signal, as sampled by the controller
interrupt status register
0 PKEU is not signaling error
1 PKEU 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 PKEU is not signaling done
1 PKEU is signaling done
Reset done. This status bit, when high, indicates that PKEU has completed its reset sequence, as reflected 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
