CHAPTER
4PERIPHERAL CIRCUITS AND OPERATION
Peripheral circuits (timer, I/O, and so on) of the S1C60N09 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 S1C60N09 Series has an address space of 160 words, of which 48 words are
allocated to display memory and 16 words, to I/O memory. Figure 4.1.1 show the overall memory map
for the S1C60N09 Series, and Table 4.1.1, the memory maps for the peripheral circuits (I/O space).

Display memory 48 words

40H–6FH = R/W
C0H–EFH = W only
Fig. 4.1.2 Display memory map
Notes: The display memory area can be selected from between 40H–6FH and C0H–EFH by mask
option.
When 40H–6FH is selected, the display memory is assigned in the RAM area. So read/write
operation is allowed.
When C0H–EFH is selected, the display memory is assigned as a write-only memory.
Memory is not mounted in unused area within the memory map and in memory area not indi-
cated in this chapter. For this reason, normal operation cannot be assured for programs that
have been prepared with access to these areas.
