Notes: *20. This output pin is forcibly set to the segment output function and held at the low level (VLCD4). However, when a “set display technique”

instruction is executed, the segment output or the common output function is selected as specified by that instruction.

*21. Since this output pin is an open-drain output, a pull-up resistor (between 1 kΩ and 10 kΩ) is required. This pin is held at the high level even if a

key data read operation is performed before executing a “set key scan output state” instruction.
