8.2.1.7 Flash ECC Master Number Register (ECSM_FEMR)
The FEMR is an 8-bit register for capturing the XBAR bus master number of the last, properly-enabled
ECC event in the flash memory. Depending on the state of the ECSM_ECR, an ECC event in the flash
causes the address, attributes and data associated with the access to be loaded into the ECSM_FEAR,
ECSM_FEMR, ECSM_FEAT and ECSM_FEDR registers, and the appropriate flag (FNCE) in the
ECSM_ESR to be asserted.
8.2.1.8 Flash ECC Attributes Register (ECSM_FEAT)
The ECSM_FEAT is an 8-bit register for capturing the XBAR bus master attributes of the last,
properly-enabled ECC event in the flash memory. Depending on the state of the ECSM_ECR register, an
ECC event in the flash causes the address, attributes, and data associated with the access to be loaded into
the ECSM_FEAR, ECSM_FEMR, ECSM_FEAT, and ECSM_FEDRs, and the appropriate flag (FNCE)
in the ECSM_ESR to be asserted.
