(2) PC1 to PC8: General-purpose output port state setting control data
This control data is used to set the high/low state of general-purpose output ports P1 to P8.

Note: PCn = 1: The output pin Pn is set high (VLCD) (n = 1 to 8).
PCn = 0: The output pin Pn is set low (VSS) (n = 1 to 8).
For example, if output pins S4/P4 and S5/P5 are selected as general-purpose output ports, setting PC4 to 1 and PC5 to 0
causes the output pin P4 to be set high (VLCD) and P5 to be set low (VSS).
