Operational Description
1. Command transfer method
1.1 Overview
(1) Commands are transferred in 8-bit units, LSB first.
Always send a first byte and a second byte (16 bits).
(2) COMMAND10 (Main screen 1 RAM write)
COMMAND11 (Main screen 2 RAM write)
COMMAND12 (Subscreen write)
COMMNAD6C1 (Color table write)
COMMAND701 (Character RAM write) is locked in continuous write mode when a continuous mode is
specified (RM2, 1 RM3). (Continuous mode is cleared by setting the CS pin high.)
1.2 Writing Data to VRAM
(1) Write start address specification
Write start address is set using:
COMMAND00, COMMAND01 (Main screen 1)
COMMAND02, COMMAND03 (Main screen 2)
COMMAND04
(Subscreen)
V4 to V0: Vertical direction; H5 to H0: 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 10-2-5 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 10-2-5
3. Write continuous (RM2 = 1, RM1 = 0): Mode 3
COM10-1 10-2-1 10-2-2 10-2-3 10-2-4 10-2-5 10-2-3 10-2-4 10-2-5
4. Write continuous (RM2 = 1, RM1 = 1): Mode 4
COM10-1 10-2-1 10-2-2 10-2-3 10-2-4 10-2-5 10-2-2 10-2-3 10-2-4 10-2-5
*: 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.
