CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (LCD Driver)
VCCHG: LCD regulated voltage switching register (FF60HD1)
Selects the reference voltage for the LCD drive voltage.
When "1" is written: VC2
When "0" is written: VC1
Reading: Valid
When "1" is written to the VCCHG register, the LCD system voltage circuit generates the LCD drive
voltage as VC2 standard. When "0" is written, it becomes VC1 standard. Select VC2 when power supply
voltage is 2.5 V or more, otherwise, select VC1.
At initial reset, this register is set to "0".
LDUTY0: LCD drive duty switching register (FF60HD2)
Selects the LCD drive duty.

At initial reset, this register is set to "0".
ALON: LCD all ON control register (FF61HD1)
Displays the all LCD dots ON.
When "1" is written: All LCD dots displayed
When "0" is written: Normal display
Reading: Valid
By writing "1" to the ALON register, all the LCD dots goes ON, and when "0" is written, it returns to
normal display.
This function outputs an ON waveform to the SEG terminals, and does not affect the content of the
display memory.
ALON has priority over ALOFF.
At initial reset, this register is set to "0".
ALOFF: LCD all OFF control register (FF61HD2)
Fade outs the all LCD dots.
When "1" is written: All LCD dots fade out
When "0" is written: Normal display
Reading: Valid
By writing "1" to the ALOFF register, all the LCD dots goes OFF, and when "0" is written, it returns to
normal display.
This function outputs an OFF waveform to the SEG terminals, and does not affect the content of the
display memory.
At initial reset, this register is set to "1".
LC3–LC0: LCD contrast adjustment register (FF62H)
Adjusts the LCD contrast.
LC3–LC0 = 0000B

::
LC3–LC0 = 1111B
dark
At room temperature, use setting number 7 or 8 as standard.
At initial reset, LC0–LC3 are undefined.
