KC1 to KC6: Sets the key scan output pin KS1 to KS6 state
Consider the case where the KS1/P1 and KS2/P2 output pins are set to function as key scan output ports. When KC1 to
KC3 are set to 1 and KC4 to KC6 are set to 0, in the key scan standby state the KS1 to KS3 output pins will output the
high level (V
DD
) and KS4 to KS6 will output the low level (V
SS
).
Note that key scan output signals are not output from output pins that are set to the low level.

PC1, PC2: Sets the general-purpose output port P1, P2 state
Consider the case where the KS1/P1 and KS2/P2 output pins are set to function as general-purpose output ports. When
PC1 is set to 1 and PC2 is set to 0, the P1 output pin will output the high level (V
DD
) and P2 will output the low level
(V
SS
).
