25.2.2.2 Bus timing for common Read/Write strobe
Remark: For separated address and data bus the signal ALE is not relevant and the
multiplexed addresses on the data bus don’t care.
For the multiplexed address and data bus the address lines A0 to A3 have to be
connected as described in chapter Automatic host controller Interface Type Detection.
