■ Address space
The memory in the MN102H series is configured as linear address space. The
instruction and data areas are not separated, so the basic segments are internal
ROM, internal RAM, and special function registers.
Figure 1-5 shows the address space for the MN102H75K/85K.The internal ROM
contains the instructions and the font data for the on-screen display (OSD), in any
location. The internal RAM contains the MCU data and the VRAM for the OSD,
in any location
.
