Freescale Semiconductor
PXR40 Microcontroller Reference Manual, Rev. 1
The data captured on a multi-bit non-correctable ECC error is undefined.
This register is read-only; any attempted write is ignored. See
for the flash
ECC data register definition.
17.2.2.12 RAM ECC Address Register (ECSM_REAR)
The ECSM_REAR is a 32-bit register for capturing the address of the last, properly-enabled ECC event in
the RAM memory. Depending on the state of the ECC configuration register, an ECC event in the RAM
causes the address, attributes and data associated with the access to be loaded into the ECSM_REAR,
ECSM_RESR, ECSM_REMR, ECSM_REAT, and ECSM_REDR registers and also the appropriate flag
(RNCE) in the ECC status register to be asserted.
This register is read-only; any attempted write is ignored. See
for the RAM
ECC address register definition.
