In the following example the NAND Flash and the external RAM (DDR2 or LPDDR or 16bit LPSDR) are NOT in the same
power supply range (NFD0_ON_D16 = 1).

This can be used if the SMC connects to the NAND Flash only. Using this function with another device on the SMC will
lead to an unpredictable behavior of that device. In that case, the default value must be selected.

At reset NFD0_ON_D16 = 1 and NAND Flash bus is connected to D16-D31.
