24.3.2.12 EEE Tag Counter Register (ETAG)
The ETAG register contains the number of outstanding words in the buffer RAM EEE partition that need
to be programmed into the D-Flash EEE partition. The ETAG register is decremented prior to the related
tagged word being programmed into the D-Flash EEE partition. All tagged words have been programmed
into the D-Flash EEE partition once all bits in the ETAG register read 0 and the MGBUSY flag in the
FSTAT register reads 0.
All ETAG bits are readable but not writable and are cleared by the Memory Controller.
24.3.2.13 Flash ECC Error Results Register (FECCR)
The FECCR registers contain the result of a detected ECC fault for both single bit and double bit faults.
The FECCR register provides access to several ECC related fields as defined by the ECCRIX index bits
in the FECCRIX register (see
