Address Multiplex
The AMX bits specify address multiplexing for
synchronous DRAM. The actual address shift value
differs between DRAM interface and synchronous
DRAM interface.
For Synchronous DRAM interface:
0000: Reserved (Setting prohibited)
0001: Reserved (Setting prohibited)
0010: Reserved (Setting prohibited)
0011: Reserved (Setting prohibited)
0100: The row address begins with A9. (The A9
value is output at A1 when the row address is
output. 64 M (1 M

0101: The row address begins with A10. (The A10
value is output at A1 when the row address is
output. 128 M (2 M
