1. Hardware Setting Conditions
2. Immediately After Reset Release
1) Assume that 1M bytes of external ROM is placed beginning at 0010 0000
2) Connect addresses A19 to A1 (1M bytes) to ROM, other addresses will use CS0.
3) Set the mode pins (MD2, MD1, MD0) to external vectors.
4) Write the reset vector to 001F FFFC
1)
2) The branch destination is set in the linker to an address in the area 001X XXXX

The following sequence describes an example using built-in RAM.
For the MB91306R, only the internal RAM area is different but the setting is same.

After reset release, the CPU will attempt to load a mode vector from 000F FFF8
FFFC
CS0 default value causes 1M bytes of external ROM to be repeated in external space, so that the mode
