10.7.5.6
The KEU interrupt status register tracks the state of possible errors, provided those errors are not masked,
through the KEU interrupt control register.
The KEU interrupt status register indicates the unmasked errors that have occurred and have generated the
ERROR interrupt signals to the channel. Each bit in this register can only be set if the corresponding bit of
the KEU interrupt mask register is zero (see
(KEUIMR)”).
If the KEU interrupt status register is non-zero, the KEU halts and the KEU ERROR interrupt signal is
asserted to the controller (see
KEU is being operated through channel-controlled access, then an interrupt signal is generated to the
channel to which the EU is assigned. The EU error then appears in the bit 55 of the channel pointer status
register (for more information, see
the controller.
This register can be cleared by setting the RI bit of the KEU reset control register. If a KEU error is reported
by the channel while operating in descriptor mode, the user can rely on the channel to clear the KEU
interrupt by writing the Continue bit in the channel configuration register (for more information, see
Section 10.4.4.1, “Channel Configuration Register
KEU to signal the corresponding error, unless the associated error has been masked in the KEU interrupt
mask register.
