Notes 1. Accessed in external memory expansion mode.
2. This 13,056-byte area can be used as internal ROM only when the LOCATION 0FH instruction is executed.
3. On execution of LOCATION 0H instruction: 183,552 bytes, on execution of LOCATION 0FH instruction: 196,608 bytes
4. Base area and entry area for reset or interrupt. However, the internal RAM area is not used as a reset entry area.
