Insert Idle Cycle
When EBI accessing continuously, there may occur bus conflict if the device access time is much
slow with system operating. EBI controller supply additional idle cycle to solve this problem.
During idle cycle, all control signals of EBI are inactive. Figure 5-117 show idle cycle as below:
There are two conditions that EBI can insert idle cycle by timing control:
By setting ExtIW2X, and ExtIR2R of register EXTIME, the time of idle cycle can be specified from
0~15 MCLK.
