3.3.1.1 – 3.3.2.1
3.3.1.1 D
Turns the display ON or OFF. The D bit takes prece-
dence over the FP bits in the parameter.
D = 0: Display OFF
D = 1: Display ON
3.3.1.2 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 perform-
ing consecutive writes to display memory while the
cursor is flashing.
3.0 Command Description
Note: If SAD4 is enabled by setting W/S to 1, FP3 and FP2
control both SAD2 and SAD4. The attributes of SAD2
and SAD4 cannot be set independently.
