10.7.4.6
The DEU interrupt status register indicates which unmasked errors have occurred and have generated error
interrupts to the channel. Each bit in this register can only be set if the corresponding bit of the DEU
interrupt mask register is zero (see
If the DEU interrupt status register is non-zero, the DEU halts and the DEU error interrupt signal is
asserted to the controller (see
DEU is being operated through channel-controlled access, then an interrupt signal is generated to the
channel to which this EU is assigned. The EU error then appears in bit 55 of the channel status register
(see
If the interrupt status register is written from the host, 1s in the value written are recorded in the interrupt
status register if the corresponding bit is unmasked in the interrupt mask register. All other bits are cleared.
This register can also be cleared by setting the RI bit of the DEU reset control register.
The definition of each bit in the DEU interrupt status register is shown in

Key Parity Error. Defined parity bits in the keys written to the key registers did not reflect
odd parity correctly. (Note that key register 2 and key register 3 are checked for parity only
if the appropriate DEU mode register bit indicates triple DES. Also, key register 3 is
checked only if key size reg = 24. Key register 2 is checked only if key size reg = 16 or 24.)
