I/O

CMOS I/O ports. Each port has an I/O select direction

or output individually.

Any port set to input can be set to use a pull-up resistor or not

by a program.

Ports P10_0 to P10_7 and P11_0 to P11_7 can be used as

LED drive ports.

Segment output

pins

CL1, CL2

Connect pins for the LCD control voltage multiplier

LCD power supply

VL1

I/O

Apply the voltage: 0

≤ VL1 ≤ VL2 ≤ VL3 ≤ VL4.

VL1 can be used as the reference potential input or output pin

when setting the voltage multiplier.
