EPROM Protect. When in ROM Protect Mode, and exe-
cuting out of External Program Memory, instructions LDC,
LDCI, LDE, and LDEI cannot read Internal Program Mem-
ory.
When in EPROM Protect Mode and executing out of Inter-
nal Program Memory, instructions LDC, LDCI, LDE, and
LDEI can read Internal Program Memory.

mode, the
memory. External data memory may be included with, or
separated from, the external program memory space.
/DM, an optional I/O function that can be programmed to
appear on pin P34, is used to distinguish between data
and program memory space (Figure 23). The state of the
/DM signal is controlled by the type of instruction being ex-
ecuted. An LDC opcode references PROGRAM (/DM inac-
tive) memory, and an LDE instruction references data
(/DM active Low) memory.
