Control Data Functions
1. CU: Normal mode current drain control data
This control data bit controls the current drain in normal mode.
CU
Current drain mode in normal mode
0
Normal current drain mode (IDD2, IDD3, IDD4, and IDD5)
1
Low current drain mode (IDD6, IDD7, IDD8, and IDD9)
However, note that the common and segment output waveforms are easily caused distortion when the low current
drain mode is selected by setting CU to 1, because in this mode the capacity to supply current to the LCD panel from
the common and segment pins is mode less than that in the normal current drain mode (CU = 0).
2. P0 to P3: Segment output port/general-purpose output port switching control data
These control data bits switch the segment output port/general-purpose output port functions of the S1/P1 to S12/P12
output pins.

When the general-purpose output port function is selected the output pins and the display data have the
correspondence listed in the tables below.

For example, when the general-purpose output port function is selected for the S4/P4 output pin, that output pin will
output a high level when display data D13 is 1, and will output a low level when D13 is 0.
