26.5.10.5 AFEU Status Register (AFEUSR)
The AFEU Status Register (AFEUSR) reflects the state of AFEU internal signals. The AFEUSR
is read-only. Writing to this location results in an address error being reflected in the AFEUISR
(see Section 26.5.10.6, AFEU Interrupt Status Register (AFEUISR), on page 26-155).

Halt
Indicates whether the AFEU is halted due to an error.
Note:
Because the error causing the AFEU to stop operating may be
masked before reaching the Interrupt Status Register, the
AFEUISR is used to provide a second source of information
regarding errors that prevent normal operation.

Error Interrupt
This status bit reflects the state of the error interrupt signal, as sampled by
the controller Interrupt Status Register (Section 26.5.4.6, Controller
Interrupt Status Register (CISR), on page 26-84).
