CHAPTER 1: OUTLINE
(7) LCD segment specification
The display memory can be allocated to the optional SEG terminal. It is also possible to set the
optional SEG terminal for DC output.
Refer to Section 4.8.4, "Mask option", for details.
(8) Synchronous clock polarity in the serial interface
The polarity of the synchronous clock SCLK and the SRDY signal in slave mode of the serial interface
is selected by the mask option. Either positive polarity or negative polarity can be selected.
Refer to Section 4.12.2, "Mask option", for details.
(9) Polarity of the buzzer output signal
It is possible to select the polarity of the buzzer signal output from the BZ terminal. Select either
positive polarity or negative polarity according to the external drive transistor to be used.
Refer to Section 4.13.2, "Mask option", for details.
(10)OSC1 oscillation frequency
Either crystal oscillation circuit or CR oscillation circuit can be selected as the OSC1 oscillation circuit.
Refer to Section 4.4.2, "OSC1 oscillation circuit", for details.
(11)OSC3 oscillation circuit
Either CR oscillation circuit or ceramic oscillation circuit can be selected as the OSC3 oscillation
circuit.
Refer to Section 4.4.3, "OSC3 oscillation circuit", for details.
<Mask option list>
The following is the option list for the S1C63358. 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.
