12.5.6
Address multiplexing is performed in line with the settings of the SPLIT bits in SDR so that
connecting the SDRAM does not require an external address-multiplexing circuit. Table 12.7
shows the relationship between the settings of SPLIT bits and address multiplexing. The number
of ROW or COL line is the addresses (bit) that are output to the address pins according to the
setting of the SPLIT bits. If a setting not specified in table 12.7 is used, correct operation is not
guaranteed.
