P0 TO P2: SEGMENT OUTPUT PORT/GENERAL-PURPOSE OUTPUT PORT
SELECTION DATA
These control data bits switch the functions of the S1/P1 to S4/P4 output pins between the segment
output port and the general-purpose output port.
Notes:
1. Sn (n=1 to 4): Segment output port
2. Pn (n=1 to 4): General-purpose output port
The table below lists the correspondence between the display data and the output pins when these
pins are selected to be general-purpose output ports.
For example, if the S4/P4 output pin is selected to be a general-purpose output port, the S4/P4 output
pin will output a high level (V
D13 is 0.
