Notes: 1. In expanded mode with ROM, bits AE3 to AE0 are initialized to B'0000.

In expanded mode with ROM, address pins A0 to A7 are made address outputs by

setting the corresponding DDR bits to 1.

2. In ROMless expanded mode, bits AE3 to AE0 are initialized to B'1101.

In ROMless expanded mode, address pins A0 to A7 are always made address output.
