⎯ 8-CAS byte control for power-down operation
⎯ DRAM control signal timing can be controlled by register settings
⎯ Consecutive accesses to the same row address
⎯ Row address/column address multiplexing according to synchronous DRAM capacity
⎯ Burst operation
⎯ Auto-refresh and self-refresh
⎯ Synchronous DRAM control signal timing can be controlled by register settings
⎯ Consecutive accesses to the same row address
⎯ Wait state insertion can be controlled by program
⎯ Burst operation, executing the number of transfers set in a register
⎯ Address/data multiplexing
⎯ SRAM interface with byte control
⎯ Wait state insertion can be controlled by program
⎯ Bus sizing function for I/O bus width
⎯ Supports refresh operation immediately after self-refresh operation in low-power DRAM
⎯ Interrupt request generated by compare-match
⎯ Interrupt request generated by refresh counter overflow
