(MPMC0/MPMC1) can be selected by setting the external pin SELMEMC (port SN0).
power supply voltage of memory interface DVCCM can be selected to correspond to 1.8 V or 3.3
V. In the case of using SDRAM, special settings for special pins and registers are required.
Required settings are shown in the table below.
This LSI contains two types of memory controller with different specifications.
Depending on the connected external memory, one of two types of controllers

input. DMCCLKP must be connected to DMCCLKIN (input pin) as short as possible in designing a board.
When using MPMC0 to control SDR SDRAM or not using SDRAM, take a precaution to avoid leak current (e.
g. fixing DMCCLKIN pin to GND).
