DDR Memory Related Pins
This section discusses the various scenarios that can be used with either of the MSC8154E DDR ports.
Note:
The signal names in Table 40, Table 41 and Table 42 are generic names for a DDR SDRAM interface. For actual pin
names refer to Table 1.

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.
If the DDR controller is not used, disable the internal DDR clock by setting the appropriate bit in the System Clock Control
Register (SCCR) and put all DDR I/O in sleep mode by setting DRx_GCR[DDRx_DOZE] (for DDR controller x). See the
Clocks and General Configuration Registers chapters in the MSC8154E Reference Manual for details.
3.
For MSC8154E Revision 1 silicon, these pins were connected to GND. For newer revisions of the MSC8154E, connecting
these pins to GND increases device power consumption.
