Section 6 Bus Controller (BSC)
Idle Cycle in Case of Normal Space Access after DRAM Space Access:
While the DRMI bit is cleared to 0 in DRACCR, idle cycle insertion after DRAM space access is
disabled. Idle cycle insertion after DRAM space access can be enabled by setting the DRMI bit to
1. The conditions and number of states of the idle cycle to be inserted are in accordance with the
settings of bits ICIS1, ICIS0, and IDLC in BCR are valid. Figures 6.76 and 6.77 show examples of
idle cycle operation when the DRMI bit is set to 1.
