MSM6665-xx

Flowchart for Power-On Timing

Turn on power

Reset input

5ms required; external reset input or power-on reset input

CS="H"

The device is enabled.

SOE/D, D0="1"

Make the SO output enable, to perform busy detection.

Wait for 20 clocks

Input a wait for the SOE/D command processing. (For the processing

of each command after this, perform busy detection. *1)

BPC and BKCG

command set

Set the blink pattern and bank change mode.

LOT, I1="1", I0="1"

Set the Load Option. (Blank-code writing and blink-cancellation

are executed each time the AINC command is executed.)

AINC executed 48 times

Input the AINC command to clear the RAM data.

LOT, I1="0", I0="0"

Release the Load Option.

Input display data for initial screen

DISP, D0="1"

Display is turned on and the initial screen is displayed.

Is Input of display data for

initial screen completed?

YES

Normal operation

After the required commands and display data are entered, perform busy detection

based on the SO pin status. When it is confirmed that the status has been changed

from BUSY (SO="L") to NON-BUSY (SO="H"), enter the next data.

If busy detection is not performed, wait for 10 master oscillation clocks when used at

1/17 duty or for 20 master oscillation clocks when at 1/9 duty, then enter the next

data.
