CSDC: LCD drive switch (0FBH D3)
Selects the LCD drive method.
When "1" is written: Static drive
When "0" is written: Dynamic drive
Reading: Valid
At initial reset, this register is set to "0".
ALLOFF: LCD all OFF control register (0FBH D2)
Fade outs the all LCD segments.
When "1" is written: All LCD segments fade out
When "0" is written: Normal display
Reading: Valid
By writing "1" to the ALLOFF register, all the LCD segments goes off, and when "0" is written, it returns
to normal display. This function does not affect the contents of the display memory.
At initial reset, this register is set to "1".
ALLON: LCD all ON control register (0FBH D1)
Displays the all LCD segments on.
When "1" is written: All LCD segments displayed
When "0" is written: Normal display
Reading: Valid
By writing "1" to the ALLON register, all the LCD segments goes on, and when "0" is written, it returns to
normal display. This function does not affect the contents of the display memory.
At initial reset, this register is set to "0".
