Commands that are supported by this LSI are NOP, auto-refresh (REF), self-refresh (SELF), all
bank precharge (PALL), row address strobe bank-active (ACTV), read (READ), write (WRIT),
and mode-register write (MRS). Commands for bank control cannot be used.
6.7.2
With continuous synchronous 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. The address-precharge-setting command (Precharge-sel) can be output on
the upper column address. Table 6.8 shows the relation between the settings of MXC2 to MXC0
and the shift size. The MXC2 bit should be set to 1 when the synchronous DRAM interface is
used.
