CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (LCD Driver)
(3) Output specification
The segment terminals (SEG0–SEG37) are selected by mask option in pairs for either segment signal
output or DC output (VDD and VSS binary output). When DC output is selected, the data corre-
sponding to COM0 of each segment terminal is output.
When DC output is selected, either complementary output or Pch open drain output can be selected
for each terminal by mask option.
Note: The terminal pairs are the combination of SEG (2
n) and SEG (2n + 1) (where n is an integer from 0 to 18).
(4) Drive bias
For the drive bias of the S1C60N13 or the S1C60L13, either 1/3 bias or 1/2 bias can be selected by the
mask option. When using the LCD system voltage regulator, it is fixed at 1/3 bias.
4.8.4 Control of LCD driver
Table 4.8.4.1 shows the LCD driver's control bits and their addresses. Figure 4.8.4.1 shows the display
memory map.

CSDC2: LCD all Off control (2D0HD0)
Controls the LCD display.
When "1" is written : LCD displayed
When "0" is written : LCD is all off
Read-out : Valid
By writing "0" to the CSDC2 register, all the LCD dots goes off, and when "1" is written, it returns to
normal display.
Writing "0" outputs an off waveform to the SEG terminals, and does not affect the content of the display
memory.
After an initial reset, CSDC2 is set to "1".
CSDC1: LCD drive switch (2E8HD3)
The LCD drive format can be selected with this switch.
When "1" is written : Static drive
When "0" is written : Dynamic drive
Read-out : Valid
At initial reset, dynamic drive (CSDC1 = "0") is selected.
