Section 6 Bus Controller (BSC)
6.7.2
With DRAM space, the row address and column address are multiplexed. In address multiplexing,
the size of the shift of the row address is selected with bits MXC2 to MXC0 in DRAMCR. Table
6.6 shows the relation between the settings of MXC2 to MXC0 and the shift size.
The MXC2 bit should be cleared to 0 when the DRAM interface is used.
