3. Output pin states during the reset period
X: don’t care
Note: *5.These output pins are forcibly set to the segment output function and held low.
KS1/S54, KS2/S55
COM1 to COM4
S1/P1 to S4/P4
*6.When power is first applied, these output pins are undefined until the S0 and S1 control data bits have been transferred.
*7.Since this output pin is an open-drain output, a pull-up resistor of between 1 and 10 kΩ is required. This pin remains high during the reset period
