4.3 Segment Ports Output Specifications
For the output specification of the segment output ports SEG0–SEG37, segment output and DC output can
be selected in units of two terminals. When used for liquid crystal panel drives, select segment output;
when used as regular output port, select DC output. When DC output is selected, either complementary
output or Pch open drain output may further be selected.
However, for segment output ports that will not be used, select segment output.
Refer to the "E0C62 Family Development Tool Reference Manual" for the segment option source file
creation.

When segment output is selected
The segment output port has a segment decoder built-in, and the data bit of the optional address in the
segment memory area (040H–06FH or 0C0H–0EFH) can be allocated to the optional segment. With this,
up to 152 segments (114 segments when 1/3 duty is selected or 76 segments when 1/2 duty is selected)
of liquid crystal panel could be driven.
The segment memory may be allocated only one segment and multiple setting is not possible.
The allocated segment displays when the bit for this segment memory is set to "1", and goes out when
bit is set to "0".
Segment allocation is set to H for high address (4–6 or C–E), to L for low address (0–F), and to D for
data bit (0–3) and are recorded in their respective column in the option list. For segment ports that will
not be used, write "---" (hyphen) in the H, L, and D columns of COM0–COM3.
Examples
• When 1/4 duty is selected
0 C00 C01 C02 C03 S
1 C10 C11 C12 C13 S
• When 1/3 duty is selected
0 C00 C01 C02 --- S
1 C10 C11 C12 --- S
• When 1/2 duty is selected
0 C00 C01 --- --- S
1 C10 C11 --- --- S
■
When DC output is selected
The DC output can be selected in units of two terminals and up to 38 terminals may be allocated for DC
output. Also, either complementary output or Pch open drain output is likewise selected in units of two
terminals. When the bit for the selected segment memory is set to "1", the segment output port goes
high (V
DD
), and goes low (V
SS
) when set to "0". Segment allocation is the same as when segment output
is selected but for the while the segment memory allocated to COM1–COM3 becomes ineffective. Write
three hyphens ("---") in the COM1–COM3 columns in the option list.
Example
• When complementary output is set to SEG34 and SEG35, and Pch open drain output is set to SEG36 and SEG37.
