Table 51. Connectivity of DDR Related Pins When the DDR Interface Is Not Used (continued)
lists unused pin connection when using 16-bit DDR memory. The 16 most significant data lines are not used.
If the DDR controller is not used, disable the internal DDR clock by writing a 1 to the CLK11DIS bit in the System Clock Control
Register (SCCR[CLK!11DIS]). See Chapter 7, Clocks, in the MSC8144 Reference Manual for details.
