The reset value of 0xFD ensures that there is a linear RAM space available between addresses 0x1000 and
0x3FFF out of reset.
The fixed 4K page from 0x2000–0x2FFF of RAM is equivalent to page 254 (page number 0xFE).
The fixed 4K page from 0x3000–0x3FFF of RAM is equivalent to page 255 (page number 0xFF).

These eight index bits are used to page 1 KByte blocks into the EEPROM page window located in the local
(CPU or BDM) memory map from address 0x0800 to address 0x0BFF (see
accessing up to 256 KByte of EEPROM (in the Global map) within the 64 KByte Local map. The
EEPROM page index register is effectively used to construct paged EEPROM addresses in the Local map
format.
