Function
Bits 27, 13-12 and 3-1 of the control register indicate an invalid SRAM memory size.
Acceptable sizes are:
4Mbit x18 unmuxed chip selects of sizes 1M, 2M, 4M.
8Mbit x18 unmuxed chip selects of sizes 2M, 4M, 8M.
16Mbit x18 unmuxed chip selects of sizes 4M, 8M, 16M.
32Mbit x18 unmuxed chip selects of sizes 8M, 16M, 32M.
4Mbit x18 muxed chip selects of sizes 2M, 4M, 8M.
8Mbit x18 muxed chip selects of sizes 4M, 8M, 16M.
16Mbit x18 muxed chip selects of sizes 4M, 16M, 32M.
32Mbit x18 muxed chip selects of sizes 8M, 32M, 64M.
4Mbit x36 unmuxed chip selects of sizes 1M, 2M.
8Mbit x36 unmuxed chip selects of sizes 1M, 2M, 4M.
16Mbit x36 unmuxed chip selects of sizes 2M, 4M, 8M.
32Mbit x36 unmuxed chip selects of sizes 4M, 8M, 16M.
4Mbit x36 muxed chip selects of sizes 1M, 2M, 4M.
8Mbit x36 muxed chip selects of sizes 2M, 4M, 8M.
4Mbit x36 muxed chip selects of sizes 4M, 8M, 16M.
8Mbit x36 muxed chip selects of sizes 8M, 16M, 32M.
Bits 17, 14, and 9-8 of the control register indicate ECC is enabled with an SRAM configu-
ration. This is invalid.
Bits 11-10 of the control register indicate a latency of three or a reserved value.
