Add Initial code
Modify ITO layout reference
Modify 9.1.14 entire display
Re-arrange sections for document format issue.
Remove one of the Power OFF flow (not easy control by customer).
Update recommend N-Line setting as 12-line (0x0A).
Rewrite some description for easy understanding and grammar issue.
Fix wrong Limiting Values.
Rewrite DC Characteristics section. Separate Internal Power Application Note for
detailed description.
Modify Recommend LCD Vop Setting: use same bias for easy use.
Modify limiting voltage values.
Modify 8080/6800 system cycle time.
Remove reversion history before Ver. 1.0.
Redraw broken figures.

Rearrange the operation flow information into one section:
“Section 10. OPERATION FLOW” (Page 48).
Rename section “10. COMMAND DESCRIPTION” to be “10. OPERATION FLOW.”
Add note of I
Add notes to Section 14. EXTERNAL COMPONENTS. Modify the value to be a range.
Different circuit for different VDD1 level (C4 is not used if VDD1 is 1.8V or 2.8V).
