• When SCKCR is written to set the clock frequencies
If an external bus release request, external access, and a refresh request occur simultaneously, the
order of priority is as follows:
When the BREQ pin is driven high, the BACK pin is driven high at the prescribed timing and the
external bus released state is terminated.
