Section 12 Bus State Controller (BSC)
Refreshing: This LSI has a function for controlling synchronous DRAM refreshing. Auto-
refreshing can be performed by clearing the RMODE bit to 0 and setting the RFSH bit to 1 in
SDCR. A continuous refreshing can be performed by setting the RRC[2:0] bits in RTCSR. If
synchronous DRAM is not accessed for a long period, self-refresh mode, in which the power
consumption for data retention is low, can be activated by setting both the RMODE bit and the
RFSH bit to 1.
