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 S1C33210 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 Controller Unit)" in "S1C33210 FUNCTION PART" in this manual.
3.2 RAM
The S1C33210 has a built-in 8KB RAM. The RAM is allocated to Area 0, address 0x0000000 to address
0x0001FFF.
The internal RAM is a 32-bit sized device and data can be read/written in 1 cycle regardless of data size (byte, half-
word or word).
