CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Memory Map)
CHAPTER
4 PERIPHERAL CIRCUITS AND OPERATION
The peripheral circuits of S1C63653 (timer, I/O, etc.) are interfaced with the CPU in the memory
mapped I/O method. Thus, all the peripheral circuits can be controlled by accessing the I/O memory on
the memory map using the memory operation instructions. The following sections explain the detailed
operation of each peripheral circuit.
4.1 Memory Map
The S1C63653 data memory consists of 512-word RAM, 1,024-word data ROM, 48-word display memory
and 70-word peripheral I/O memory. Figure 4.1.1 shows the overall memory map of the S1C63653, and
Table 4.1.1 the peripheral circuits' (I/O space) memory maps.

Note: Memory is not implemented in unused areas within the memory map. Further, some non-imple-
mentation areas and unused (access prohibition) areas exist in the peripheral I/O area. If the
program that accesses these areas is generated, its operation cannot be guaranteed. Refer to the
I/O memory maps shown in Table 4.1.1 for the peripheral I/O area.
