MEMORY WRITE BMODE
Note 1 For successive write operations MWR remains high
Note 2 One idle clock cycle (Ti) will be inserted between the last write cycle and the following read cycle in RDA and TDA operation Note that the data bus will
become TRI-STATE from the rising edge of the clock after the idle cycle (see T52 for BSCK to data TRI-STATE timing)
