MEMORY READ BMODE
Note 1 For successive read operations MWR remains low and for successive write operations MWR remains high During RBA and TBA transfers the MWR
signal will stay either high or low for the entire burst of the transfer During RDA and TDA transfers the MWR signal will switch on the rising edge of a Ti (idle) state
that is inserted between the read and the write operation
Note 2 DSACK0 1 must be synchronized to the bus clock (BSCK) during synchronous mode
