Specification Overview of LCD Drive Control Circuit (1)
The frequency of the internal signal LCDCK for determing the LCD drive timing:
Frame frequency:
Max. 56 pins (SEG0 to SEG55)
• Pins SEG0 to SEG51 can be individually controlled for use as an I/O port or a segment output pin.
• Pins SEG52 to SEG55 can be individually controlled for use as an I/O port or a common
Max. 8 pins (COM0 to COM7)
• The common output pins can be selected.
• Pins COM0 to COM3 can be used I/O ports when not in use as common output pins.
• Pins COM4 to COM7 can be individually controlled for use as an I/O port or a segment
External division resistors or the internal voltage multiplier can be used
(1) When external division resistors are used
• The LCD drive voltage is applied to LCD power supply pins VL1 to VL4 using external
• The following voltage values are applied to LCD power supply pins VL1 to VL4 based on
Note:
The R8C/L35A Group and R8C/L35B Group do not have the VL3 pin, so 1/4 bias cannot
be selected.
(2) When the internal voltage multiplier is used
• 1/4 or 1/2 bias selected:
• 1/3 bias selected:
• The VL1 voltage can be generated internally or input externally.
Note:
The R8C/L35A Group and R8C/L35B Group do not have the VL3 pin, so 1/4 bias and 1/2
bias cannot be selected.

the bias values set by the LCR0 register.
Based on the VL1 voltage, two times the voltage is generated at the VL2 pin, three times
the voltage at the VL3 pin, and four times the voltage at the VL4 pin.
Based on the VL1 voltage, two times the voltage is generated at pins VL2 and VL3, and
three time the voltage at the VL4 pin.
