3 Internal Memory
This chapter explains the internal memory configuration.
Figure 3.1 shows the S1C33L03 memory map.
Area 2 is used in debug mode only and it cannot be accessed in user mode (normal program execution status).

3.1 ROM and Boot Address

The S1C33L03 does not have a built-in ROM. The boot address is fixed at 0x0C00000, and so external ROM/Flash
should be used in Area 10.
For setting up Area 10, refer to the "BCU (Bus Control Unit)" in "S1C33L03 FUNCTION PART" in this manual.
