6-3 Display Control Commands
6-3-1 DISP ON/OFF
Turn the whole display on or off. The single-byte parameter enables and disables the cursor and
layered screens, and sets the cursor and screen flash rates. The cursor can be set to flash over
one character or over a whole line.
6-3-1-1 D
Turn the display ON or OFF. The D bit takes precedence over the FP bits in the parameter.
D = 0: Display OFF
D = 1: Display ON
6-3-1-2 FC
Enables/disables the cursor and sets the flash rate. The cursor flashes with a 70% duty cycle
(ON/OFF).
Note: As the MWRITE command always enables the cursor, the cursor position can be checked
even when performing consecutive writes to display memory while the cursor is flashing.
