This section describes the pins of the LCD controller.
Pins of LCD Controller
The pins related to the LCD controller are: 4 common output pins (COM0 to COM3), 28 segment
output pins (SEG0 to SEG23, SEG28 to SEG31), and 4 LCD drive power supply pins (V1 to V3).
The number of segment output pins differs for each MCU series.
To use these pins for the LCD, set the corresponding bits in the LCDC enable registers (LCDCE1
to 5) to "1".
To use LCD pins for ports, set the PICTL bit in LCDC enable register 1 (LCDCE1) to "1" and the
corresponding select bits (COM/SEG) in LCDC enable registers 1 to 5 to "0".
COM0 to COM3 pins
The COM0 to COM3 pins are LCD common outputs.
These pins also serve as I/O ports.
SEG0 to SEG23, SEG28 to SEG31 pins
The SEG0 to SEG23, SEG28 to SEG31 pins are LCD segment output pins.
The number of segment output pins depends on each MCU series.
These pins also serve as I/O ports.
V1 to V3 pins
these pins are used as the power supply pins for driving the LCD.
These pins also serve as I/O ports.
