and the upper 3 bits containing the register subindex
within that module. Any time that it is necessary to
directly select one of the upper 24 index locations in a
destination module, the prefix register PFX is needed to
supply the extra destination bits. This prefix register
write is inserted automatically by the assembler and
requires only one additional execution cycle.
Memory Organization
The device incorporates several memory areas:
2kWords of utility ROM
1kWords of EEPROM for program storage
128 bytes of EEPROM for data storage
64 bytes of SRAM for storage of temporary variables
4-level stack memory for storage of program return
addresses and general-purpose use
The memory is arranged by default in a Harvard archi-
tecture, with separate address spaces for program and
data memory. A special pseudo-Von Neumann memory
mode allows data memory to be mapped into program
space, permitting code execution from data memory.
This places the utility ROM, code, and data memory
into a single contiguous memory map. This is useful for
applications that require dynamic program modification
or unique memory configurations. In addition, another
mode allows program memory to be mapped into data
space, permitting code constants to be accessed as
data memory.
The incorporation of EEPROM for program storage allows
the devices to be reprogrammed, eliminating the expense
of throwing away one-time programmable devices during
development and field upgrades. EEPROM can be pass-
word protected with a 16-word key, denying access to
program memory by unauthorized individuals.
