9 0 AC and DC Specifications
MEMORY WRITE BMODE
Note 1 DS will only be asserted if the bus cycle has at least one wait state inserted
Note 2 For successive write operations MRW remains low
Note 3 DSACK0 1 must be synchronized to the bus clock (BSCK) during synchronous mode
Note 4 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)
