For example, you might be developing a system with the following
characteristics:
input port at 500 hex
output port at 580 hex
program and data in external ROM from c000 through
dfff hex
Suppose that the only thing that exists in your target system at this time
are input and output ports and some control logic; no memory is
available. You can reflect this by mapping the I/O ports to target
system memory space and the rest of memory to emulation memory
space. Type the following commands:
R> map -d *
R> map 500..580 tram
R> map 0c000..0dfff erom
R> map
# remaining number of terms : 14
# remaining emulation memory : 7df00h bytes
map 0000500..00005ff tram # term 1
map 000c000..00dfff eram # term 2
map other tram
As you can see, the mapper rounded up the second term to 256 bytes
block, since those are minimum size blocks supported by the HP
64147A 7750/51 Series emulator.
Note
When you use background monitor, the emulator occupies 2K byte,
which is used for background monitor program, leaving 122K, 506K,
1018K, 2042K byte of emulation memory which you may use.
Note
When you emulate the internal ROM area, you must map the address
to emulation memory.
