Control Data Functions
1. KC1 to KC6: Key scan output state setting data
These control data bits set the states of the key scan output pins KS1 to KS6.
For example, if KC1 to KC3 are set to 1, and KC4 to KC6 are set to 0, then the output pins KS1 to KS3 will output high
levels (V
DD
) and the output pins KS4 to KS6 will output low levels (V
SS
) in the key scan standby state.
Note that key scan output signal is not output from output pins that are set low.
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
).

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

level.
The display contrast adjustment circuit operates, and the display contrast is adjusted.
