Notes:
1 If the next transfer is DMA, null periods between memory transfers can occur. 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[3:2]
– 32-bit port = BE[3:0]
3 Port size determines which CAS signals are active:
– 8-bit port = CAS3*
– 16-bit port = CAS[3:2]
– 32-bit port = CAS[3:0]
4 The TA* and TEA*/LAST signals are for reference only.
