25.4.2
The DDR interface has two debug modes distinguished by which pins drive the debug information. In one
mode, debug information (source ID, data valid) is multiplexed onto the ECC pins; the other mode uses
the debug pins.
25.4.2.1
If MSRCID0 is high when sampled during POR, the debug information from the DDR SDRAM interface
is driven on MSRCID[0:4] and MDVAL. This POR value is captured in PORDBGMSR[MEM_SEL] as
described in
source ID appears on MSRCID[0:4] during a RAS or CAS cycle. During any other cycle, the value of
MSRCID[0:4] is all ones, which indicates idle cycles on the address/command interface. Similarly,
MDVAL is asserted during valid data cycles on the DDR interface.
25.4.2.2
If MSRCID1 is low when sampled during POR, debug information from the DDR SDRAM interface is
selected to appear on MECC[0:5] as shown in
(the source ID), appears on MECC[0:4] during a RAS or CAS cycle. During any other cycle the value of
MECC[0:4] is all ones. A data-valid signal (DVAL) is driven on MECC5 during valid DDR SDRAM data
cycles.

In this mode, MECC[0:5] must be disconnected from all SDRAM devices
to prevent contention on those lines.
