14. Reset Command
This command resets the register and counter of the display data RAM as follows. This does not affect the contents
of the display data RAM.
After resetting, display starts according to the reset value.
Resets the display start line register to the 1st line.
Resets the column address counter to address 0 (00
H
).
Resets the page address counter to page 0.
Clears the serial interface counter.
Turns OFF the Read Modify Write.
15. Bias Select
Selects a built-in LCD bias resistor.
When the LCD power supply circuit ON/OFF command is ON, LCD drive waveform of the selected value of the bias
is output.
When the LCD power supply circuit ON/OFF command is OFF, a built-in LCD bias resistor is disconnected and the
command is invalid.
16. LCD Voltage Command Fine Adjustment Data Set
Minutely adjusts voltage adjustment circuit output V5 with the corresponding command.
When this fine adjustment circuit is in no use, set the fine adjustment data to (0, 0, 0, 0).
