Operational Description
Command transfer method
Overview
(1) Commands are transferred in 8-bit units, LSB first.
Always send a first byte and a second byte (16 bits).
(2) Command 10 (Main RAM write)
Command 11 (Wallpaper write)
Command 71 (Color table write)
When these commands specify continuous mode (RM2, 1 RM3), the IC is locked in continuous write mode.
(Continuous write mode is cleared by setting the CS pin high.)
Writing data to VRAM
(1) Write start address specification
Use command 00 to set the write start address.
V3:0: Vertical direction, H5:0: Horizontal direction
(2) Data write
Continuous write mode differs depending on the write mode specification. (RM1, RM2)
1. Normal (RM2 = 0, RM1 = 0: initial state) *Continuous mode not used*
-- COM10-1 10-2-1 10-2-2 10-2-3 10-2-4 command wait state --
2. Write continuous (RM2 = 0, RM1 = 1): Mode 2
COM10-1
10-2-1 10-2-2 10-2-3 10-2-4
3. Write continuous (RM2 = 1, RM1 = 0): Mode 3
COM10-1 10-2-1 10-2-2 10-2-3 10-2-4
10-2-3 10-2-4
4. Write continuous (RM2 = 1, RM1 = 1): Mode 4
COM10-1 10-2-1 10-2-2 10-2-3 10-2-4
10-2-2 10-2-3 10-2-4
*: In modes 2, 3, and 4, the IC remains locked in continuous write mode until the CS pin is set high.
The write address is automatically incremented.
The write address is retained unless the IC is reset or a new write address is issued.
