CHAPTER 1: OUTLINE
(9) OSC3 oscillation circuit
Either CR oscillation circuit or ceramic oscillation circuit can be selected as the OSC3 oscillation circuit.
Refer to Section 4.3.3, "OSC3 oscillation circuit", for details.
<Mask option list>
The following is the option list for the S1C63455. Multiple selections are available in each option item as
indicated in the option list. Refer to Chapter 4, "Peripheral Circuits and Operation", to select the specifica-
tions that meet the application system. Be sure to select the specifications for unused functions too,
according to the instruction provided. Use winfog in the S5U1C63000A package for this selection. Refer to
the "S5U1C63000A Manual" for details.
