Flash ECC Attributes Register (FEAT)
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 also the appropriate flag (FNCE) in the ECC status register to be
asserted.
This register is read-only; any attempted write is ignored. See
for the flash
ECC attributes register definition.
