Notes
External Memory except the top eight bytes (FF:FFF8H–FF:FFFFH) which are
reserved for the configuration array.
External memory or on-chip nonvolatile memory (8Kbytes FF:0000H - FF:1FFFH,
16Kbytes FF:0000H - FF:3FFFH).

NOTES:
1.
18 address lines are bonded out (A15:0, A16:0, or A17:0 selected during chip configuration).
2.
The special function registers (SFRs) and the register file have separate internal address spaces.
3.
Data in this area is accessible by indirect addressing only.
4.
Devices reset into internal or external starting locations depending on the state of EA# and configura-
tion byte information See EA#. See also UCONFIG1:0 bit definitions in the 8XC251SA/SB/SP/SQ
Embedded Microcontroller User’s Manual.
5.
The 16-Kbyte ROM/OTPROM/EPROM devices allow internal locations FF:2000H–FF:3FFFH to map
into region 00:. In this case, if EA# = 1, a data read to 00:E000H–00:FFFFH is redirected to internal
ROM/OTPROM/EPROM (see bit 1 in UCONFIG0). This is not available for 8-Kbyte
ROM/OTPROM/EPROM devices.
6.
This reserved area returns indeterminate values.
7.
Data is accessible by direct and indirect addressing.
8.
Data is accessible by direct, indirect, and bit addressing.
9.
Data is accessible by direct, indirect, and register addressing.
10. Eight addresses at the top of all external memory maps are reserved for current and future device
configuration byte information.
External Memory

External memory or with configuration bit EMAP# = 0, addresses in this range
access on-chip code memory in region FF: (16 Kbyte devices only).
