REJ09B0325-0300
RFSH signal output for refresh control
Software-selectable refresh interval
Software-selectable self-refresh mode
Wait states can be inserted
Refresh timer counter (RTCNT) can be used as an 8-bit up-counter
Selection of seven counter clock sources: /2, /8, /32, /128, /512, /2048, /4096
Interrupts can be generated by compare match between RTCNT and the refresh time constant
register (RTCOR)
