Switches the entire display ON or
OFF, regardless of the Display
RAM’s data or the internal status. *
Determines the line of RAM data to
be displayed at the display’s top
line (COM0)
Sets the page of the Display RAM
in the page address register.
Sets the column address of the
Display RAM in the column
address register.
Read the status.
Busy 1: Busy (internal processing)
0: Ready status
ADC 1: Rightward (forward) output
0: Leftward (reverse) output
ON/OFF 1: Display OFF
0: Display ON
RESET 1: Resetting. 0: Normal
Writes the
data on the
data bus to
RAM
Reads data
from the
Display
RAM onto
the data
bus.
Used to reverse the
correspondence between the
Display RAM’s column address and
segment driver output ports
0: Rightward (forward)output
1: Leftward (reverse) output
Selects normal display operation or
static all-lit drive display operation.
