Figure 1 ROM Memory Map
RAM Memory Map
The MCU has on-chip RAM comprising a memory register area, data area, and stack area. In addition to
these areas, an interrupt control bit area, special register area, and register flag area are mapped onto RAM
memory space as a RAM-mapped register area.The RAM memory map is shown in figure 2 and described
below.
After power supply has been connected, regardless of a reset, the values for the memory register,
data and stack areas will be undefined. Make sure to initialize prior to use.
