Control Data Functions
For example, if PC1 and PC2 are set to 1, and PC3 and PC4 are set to 0, then the output pins P1 and P2 will output high
levels (V
DD
) and the output pins P3 and P4 will output low levels (V
SS
).
1. PC1 to PC4: General-purpose output port state setting data
These control data bits set the states of the general-purpose output ports P1 to P4.

CTC: Display contrast adjustment circuit state setting
Note that although the display contrast can be adjusted by operating the built-in display contrast adjustment circuit, it is
also possible to apply fine adjustments to the contrast by connecting an external variable resistor to the V
LCD
4 pin and
modifying the V
LCD
4 pin voltage. However, the following conditions must be met: (V
LCD
0 – V

CTC
Display contrast adjustment circuit state
0
The display contrast adjustment circuit is disabled, and the V
LCD
0 pin level is forced to the V
LCD
level.
The display contrast adjustment circuit operates and the display contrast is adjusted.
