Control Data Functions
1.KP1, KP2: Selection data between the key scan output ports and the general-purpose output ports.
These control data bits switch the functions of the KS4/P4 to KS6/P2 output pins between the key scan output port and
the general-purpose output port.
2.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.
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 (VDD) and the KS4 to KS6 pins will output the low level (VSS). Note that key scan output signals are not output
from output pins that are set to the low level.
Note: KSn (n = 4 to 6): Key scan output ports
Pn (n = 4 to 2): General-purpose output ports
No. 7632-8/16

3.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.
For example, if the KS4/P4 to KS6/P2 output pins are set to function as general-purpose output ports, when PC1 and
PC2 are set to 1, and PC3 and PC4 are set to 0, the P1 and P2 output pins will output the high level (VDD), and P3 and
P4 will output the low level (VSS).
