8.2.1.14 RAM ECC Data High Register (ECSM_REDRH)
The ECSM_REDRH and ECSM_REDRL are 32-bit registers for capturing the data of the last,
correctly-enabled ECC event in the RAM memory. Depending on the state of the ECSM_ECR, an ECC
event in the RAM loads the address, attributes and data of the access into the ECSM_REAR,
ECSM_REMR, ECSM_REAT, ECSM_REDRH and ECSM_REDRL registers, and asserts the RFNCE
flag in ECSM_ESR.
