Notes:
1
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]
2
The precharge and/or active commands are not always present. These commands depend on
the address of the previous SDRAM access.
3
The TA* and TEA*/LAST signals are for reference only.
