output port at 0f100 hex
program and data from 1000 through 3fff 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 0f000..0f100 tram
R> map 1000..3fff eram
R> map
# remaining number of terms : 14
# remaining emulation memory : 7e800h bytes
map 001000..003fff eram # term 1
map 00f000..00f1ff tram # term 2
map other tram
As you can see, the mapper rounded up the second term to 512 bytes
block, since those are minimum size blocks supported by the H8/3003
emulator.
Note
When you use the internal ROM, you must map that area to emulation
memory. When you power on the emulator, all memory space except
internal RAM is mapped to target RAM. Therefore, if you don’t map
internal ROM properly, you cannot access that area.
