7.15.4
An immediate access cycle consists of one address phase and one data phase. A block transfer with address increment
enabled consists of several consecutive address/data phase couples. A block transfer with disabled address increment
consists of one address phase followed by several data phases. The AS_ALE signal toggles only for a new address
phase.The single bytes or words are assembled/disassembled to/from Dwords. This includes byte lane swapping since
8-bit devices use for data transfer AD7 to AD0 only, (AD15 to AD8 are used in address phase too, since all 16 AD lines
are used for addressing.)
