3.5.1.2
DDR Interface Is Used With 32-Bit DDR Memory Only
Table 41 lists unused pin connection when using 32-bit DDR memory. The 32 most significant data lines are not used.
3.5.1.3
ECC Unused Pin Connections
When the error code correction mechanism is not used in any 32- or 64-bit DDR configuration, refer to Table 42 to determine
the correct pin connections.

Notes:
1.
For the signals listed in this table, the initial M stands for M1 or M2 depending on which DDR controller is not used.
2.
For MSC8156 Revision 1 silicon, these pins were connected to GND (or VDD). For newer revisions of the MSC8156,
connecting these pins to GND increases device power consumption.
