Segment outputs for displaying the display data transferred by serial data input.
The S1/P1 to S4/P4 pins can be used as general-purpose output ports when so set
up by the control data.
Common driver outputs. The frame frequency is fo [Hz].

Display off control input
? INH = low (VSS) ...Display forced off
S1/P1 to S4/P4 = low (VSS)
(These pins are forcibly set to the segment output port function
and held at the VSS level.)
S5 to S27 = low (VSS)

COM1, COM2 = low (VSS)
OSC = Z (high impedance)

RC oscillation stopped
Inhibits external clock input.
? INH = high (VDD)...Display on
RC oscillation enabled (RC oscillator operating mode)
Enables external clock input (external clock operating mode)
However, serial data transfer is possible when the display is forced off.
