10.7.7.7
The 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 PKEU
interrupt mask register is zero (see
If the PKEU interrupt status register is non-zero, the PKEU halts and the PKEU error interrupt signal is
asserted to the controller (see
PKEU 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 PKEU reset control register.
