Description
High address byte is placed on the bus if the extended write is used.
Low address byte is put out.
1 clock period for address is set up.
ALE goes high to enable latch. This will extend to 2 clocks wide if IORDY# is low.
ALE goes low to latch address and CS# is set active low.
Data driven onto the bus.
1 clock period for data setup.
WR# is driven active low. This will extend to 6 clocks wide if IORDY# is low.
WR# is driven inactive high.
CS# is driven inactive, 1/2 a clock period after WR# goes inactive
Data is held until here and may now change
