Description
Flash ECC Master Number Register
This 4-bit register contains the AXBS bus master number of the faulting access of the last,
properly-enabled flash ECC event.
16.4.2.13 Flash ECC Attributes (FEAT) register
The FEAT is an 8-bit register for capturing the AXBS bus master attributes of the last, properly-enabled
ECC event in the flash memory. Depending on the state of the ECC Configuration Register, an ECC event
in the flash causes the address, attributes and data associated with the access to be loaded into the FEAR,
FEMR, FEAT and FEDR registers, and the appropriate flag (F1BC or FNCE) in the ECC Status Register
to be asserted.
This register can only be read from the IPS programming model; any attempted write is ignored. See
Figure 16-12 and Table 16-13 for the Flash ECC Attributes Register definition.

16.4.2.14 Flash ECC Data Register (FEDR)
The FEDR is a 32-bit register for capturing the data associated with the last, properly-enabled ECC event
in the flash memory. Depending on the state of the ECC Configuration Register, an ECC event in the flash
causes the address, attributes and data associated with the access to be loaded into the FEAR, FEMR,
