Notes:
1
At least one null period occurs between memory transfers. More null periods can occur if the
next transfer is DMA. Thirteen clock pulses are required for DMA context switching.
2
Port size determines which byte enable signals are active:
–
8-bit port = BE3*
–
16-bit port = BE[3:0]
–
32-bit port = BE[3:0]
3
The TW cycles are present when the WAIT field is set to 2 or more.
4
The TA* and TEA*/LAST signals are for reference only.
