In debug mode, the high-order 5 bits (MECC[0:4]) may be used to provide the transaction
source ID and MECC5 can be used as the data-valid indicator.
In debug mode, MECC[0:5] is constantly driven with debug information and must be
disconnected from the DDR memory’s ECC pins.

to which the debug information applies is specified during POR with MSRCID0 as shown in
