This is a register available to software to attach an identifier to a transaction in progress. This handle will be
available from the ECC register space when the completion interrupt occurs.
Always write zeroes to this bit field.

Always write zeroes to this bit field.
ECC buffer information. The BCH error correction only allows two configurations of the buffer mask - software
may either read just the first block on the flash page or the entire flash page. Write operations must be for
the entire flash page. Invalid buffer mask values will cause the DMA descriptor command to be terminated.
