SEGMENT OPTION GENERATOR SOG62XX
S1C62 FAMILY EPSON VI-5
DEVELOPMENT TOOL REFERENCE MANUAL
Each SEG port number corresponds to an actual device, so it must be unique. Moreorve, data descrip-
tions in accordance with the following format are required for segments SEG0–SEG25.
Off areas COM0 to COM3, write three successive "---" (3 hyphens) as data for unused areas. SEG port
numbers are needed even if the ports themselves will not be used, so write "---" (3 hyphens) for all areas
COM0 to COM3.
Example: When not using COM2 in SEG8
8_981_980_---_A22
Example: When not using SEG12
12_---_---_---_---
When "DC output" is selected, write the segment memory-SEG ports correspondence data for COM0;
"---" (hyphens) for COM1 to COM3.
Example: When outputting SEG20 and SEG21 as DC output
20_933_---_---_---
21_A33_---_---_---
Symbol "_" indicates a blank or tab. Be sure to write one or more blanks or a tab between the SEG port
number, COM0, COM1, COM2, and COM3.
Output specification selection data
This data is used to specify whether the SEG port will be used as a segment output port, a DC comple-
mentary output port, or a DC open drain output port.
Write data after inserting one or more blanks or a tab after the segment memory-SEG ports correspond-
ence data.
S: Segment output
C: DC complementary output
P: DC Pch open drain output
N: DC Nch open drain output
The SEG port output specifications must be selected in units of two ports, so write the selection data
carefully while referencing the option list.
Example: When outputting SEG22 and SEG23 as DC complementary output
22_AE0_---_---_---_C
23_AF0_---_---_---_C
Select "SEG output" for the segment ports that will not be used.
Example: When not using SEG18
18_---_---_---_---_S
Note Only complementary output is enabled as the DC output of the SEG ports of evaluation board.
Therefore, complementary output is enabled even if open drain output is selected. Respond to it by
adding external circuits as required.
Generate the segment option source file according to the formats and restrictions above.
Either one is set, depending on the model.
