CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (LCD Driver)
LPAGE: LCD display memory selection register (FF61HD0)
Selects the display memory area at 1/8 duty drive.
When "1" is written: F100H–F177H
When "0" is written: F000H–F077H
Reading: Valid
By writing "1" to the LPAGE register, the data set in F100H–F177H (the second half of the display
memory) is displayed, and when "0" is written, the data set in F000H–F077H (the first half of the display
memory) is displayed.
This function is valid only when 1/8 duty is selected, and when 1/16 or 1/17 duty is selected, this
register can be used as a general purpose register.
At initial reset, this register is set to "0".
LC3–LC0: LCD contrast adjustment register (FF62H)
Adjusts the LCD contrast.
LC3–LC0 = 0000B
light
::
LC3–LC0 = 1111B
dark
At room temperature, use setting number 7 or 8 as standard.
At initial reset, LC0–LC3 are undefined.
4.7.8 Programming notes
(1) When a program that access no memory mounted area (F078H–F0FFH, F178H–F1FFH, F201H, F203H,
, F277H) is made, the operation is not guaranteed.
(2) Because at initial reset, the contents of display memory and LC3–LC0 (LCD contrast) are undefined,
there is need to initialize by the software. Furthermore, take care of the registers LPWR and ALOFF
because these are set so that the display goes OFF.
