Description
Address Inputs – (MSB:0, LSB:28)
Input Least significant address bit when asynchronous SRAMs are used.
Input Next to least significant address bit when asynchronous SRAMs are used.

Clock Inputs – CLK2 is for Tag RAM, CLK0, 1, 3, and 4 are for SRAMs.
For 1MB use all the clocks. For 512KB or less us CLK0–CLK2 only.
High Data Bus – (MSB:0, LSB:31)
I/O Low Data Bus – (MSB:0, LSB:31)
