KC1 to KC6: Sets the key scan output pin KS1 to KS6 state
Output pin
KS1 KS2 KS3 KS4 KS5 KS6
Key scan output state setting data KC1 KC2 KC3 KC4 KC5 KC6
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 (VDD) and the output pins KS4 to KS6 will output low levels
(VSS) in the key scan standby state.
Note that key scan output signals are not output from output pins that are set low.
• Set general-purpose output port state ... <Sets the states of the general-purpose output ports>
Code
D56 D57 D58 D59 D60 D61 D62 D63
PC1 PC2 PC3 PC4 1 0 1 0
PC1 to PC4: Sets the general-purpose output port P1 to P4 state
Output pin
General-purpose output port state setting data
P1 P2 P3 P4
PC1 PC2 PC3 PC4
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 (VDD) and the output pins P3 and P4 will output low levels (VSS).
No. 6144-19/43
