CHAPTER 4: PERIPHERAL CIARCUITS AND OPERATION (Memory Map)
CHAPTER
4PERIPHERAL CIRCUITS AND OPERATION
Peripheral circuits (timer, I/O, and so on) of the S1C6N3B0 Series are memory mapped. Thus, all the
peripheral circuits can be controlled by using memory operations to access the I/O memory. The follow-
ing sections describe how the peripheral circuits operate.
4.1 Memory Map
The data memory of the S1C6N3B0 Series has an address space of 150 words, of which 32 words are
allocated to display memory and 22 words, to I/O memory. Figure 4.1.1 show the overall memory map
for the S1C6N3B0 Series, and Tables 4.1.1(a)–(b), the memory maps for the peripheral circuits (I/O space).

Note: Memory is not mounted in unused area within the memory map and in memory area not indicated
in this chapter. For this reason, normal operation cannot be assured for programs that have been
prepared with access to these areas.
