2.4 Code Memory Operations

Code memory is a 16-bit address space that corresponds to the masked ROM of the volume production
device. The emulator starts with a code memory area the size of the ROM in the microcontroller
specified with the dedicated emulator setup utility.

2.4.1 Data Operations between Code Memory and Disk Files

These operations include copying data in either direction between code memory and disk files.
They always involve simultaneous use of a pair of object files: one for the upper 8 bits and another for
the lower 8 bits.

2.4.2 Data Operations between Code Memory and EPROMs

These operations limit copying data to one direction: from EPROMs in the two sockets on top of the
emulator to code memory.
The socket labeled EPROM.HIGH is for the upper 8-bit object file (.HXH) from the assembler;
EPROM.LOW, the lower 8-bit object file (.HXL).
The emulator cannot program EPROMs. Use a commercial EPROM writer to write the two object files
generated by the dedicated assembler to separate EPROMs.
