(3) Setting segment outputs
The LCD drive circuit of an S1C63 Family chip that has had segment options set normally allows
selecting the segment output and DC output for every two pins (in certain types of microcomputers,
individually for each pin). Segment output should be specified when using the pins for driving an
LCD panel.
Segment output ports have a built-in segment decoder allowing any address and data bit in the
display memory area to be assigned to any segment. When the segment memory bit is set to 1, the
assigned segment lights up; when the bit is set to 0, the segment dims. Segments and display memory
bits correspond individually, so that you cannot assign one display memory bit to multiple segments.
Therefore, all segments must be assigned different addresses and data bits.
For details about the display memory map and segment assignment, refer to the Technical Manual for
each type of microcomputer.
In the explanation below, the chip is assumed to have four common pins, COM0 to COM3.
Follow the procedure below to assign segments:
1. From the [Memory Address/Data bit] table, select the memory address/data bit you want to
assign by clicking the appropriate cell. The cell changes color to blue.
If you select an incorrect cell, select a correct cell.
The horizontal rows of the table correspond to display memory addresses. The hexadecimal
number shown to the right of the "Memory Address/Data bit" title is the base address of display
memory, with only the lower byte of address being displayed in each row of the table. The vertical
columns of the table correspond to data bits.
