19.2.2
As its on-chip ROM, the H8/3048F has 128 kbytes of flash memory. The flash memory is
connected to the CPU by a 16-bit data bus. The CPU accesses both byte data and word data in two
states.
The flash memory is assigned to addresses H'00000 to H'1FFFF on the memory map. The mode
pins enable either on-chip flash memory or external memory to be selected for this area. Table
19.3 summarizes the mode pin settings and usage of the flash memory area.
