In a low temperature environment (below 0°C), speed and contrast decrease when image changes. The non-indicator dot may become dense in
a high temperature environment (about +50°C). Highest backlight brightness level should not be used for temperatures above +35°C.

SPI Timing Chart (SS Using)
It is recommended that all SS pins be connected to a controller pin
instead of ground. A clock glitch during power up could cause the
communication to fall out of sync. Toggling the SS line resets the
communication.

COMMANDS & DATA
• Transferring display data/displaying on LCD: command (1 Byte) + data (256 Bytes)
Rockers
• Others: command (1 Byte) + data (1 Byte)
• Commands can be accepted only when all bits coincide; otherwise, they are not acknowledged
• Additional commands will not be received until the communication of commands (1 Byte) and data (256 or 1 Byte) is completed
• There is no time limit from the beginning to end of data receipt
• Commands may be executed consecutively (no need to wait between commands)
• Irregular commands or data are not recognized
• Initial status at power activation: LCD display off, LED off (brightness 1/20, color off)
